Duration:
Full-Day, Friday, Dec 5th
Instructors:
Prof. Leonard J. Cimini, Jr., Dept. of Elect. and Comp. Eng, University
of Delaware, USA
Prof. Gordon Stber, School of Elect. and Comp. Eng., Georgia Institute

Description:
Orthogonal frequency division multiplexing (OFDM) has been shown to be
an effective technique to combat multipath fading in wireless communications.
This approach has been chosen as the standards in several outdoor and
indoor high-speed wireless data applications. The capacity of wireless
communication systems can be further improved if the recent emerging MIMO
techniques are used in OFDM systems. This tutorial initially presents
the basic principles of OFDM, and discusses the problems and some of the
potential solutions to the practical issues in implementing such a system,
including techniques for peak-to-average power ratio reduction, time and
frequency synchronization, channel estimation, adaptive antenna arrays
and transmitter diversity. Then we briefly introduce MIMO techniques and
present the application of these techniques to OFDM wireless communication
systems. We conclude with a discussion of current and proposed systems.

CDMA2000 1xEV-DV
Duration:
Half-Day, Monday Morning, Dec 1st
Instructors:
Mr. David Comstock, Ericsson Wireless Communications, Inc., USA
Dr. Anthony C. K. Soong, Ericsson Wireless Communications, Inc.,
USA
Dr. Rath Vannithamby, Ericsson Wireless Communications, Inc., USA
Description:
The wireless communication industry is currently in a state of transition
from second generation (2G) to third generation (3G) systems --
a move from circuit-switched, mainly voice services to multi-media
services that include voice, packet data and video. The CDMA2000
family of standards is based upon code division multiple access
(CDMA) technology and is one of the defined modes in the International
Telecommunication Union (ITU) 3G wireless standard. The early revisions
of the CDMA2000 standard support high-speed data transmission (up
to 643.2 kbps) using dedicated data channels. The latest revision,
Revision C, significantly increases the efficiency of the air interface
by introducing a high-speed shared packet data channel (with a peak
data rate of 3.091 Mbps) while maintaining backward compatibility
with previous revisions. This revision, commonly referred to as
1xEV-DV (for 1xRTT Evolution for high-speed integrated Data and
Voice), was approved in May 2002 by the Telecommunication Industry
Association (TIA) and submitted to ITU for inclusion in the next
revision of its 3G standard. The 3GPP2 Standards group is presently
engaged in the development of reverse link enhancements for a future
Revision D scheduled for completion by September 2003. This tutorial
covers a number of key features of 1xEV-DV in terms of Revision
C and the anticipated Revision D. The former includes the design
of the high-speed shared data channel, its components (Hybrid-ARQ,
link adaptation, modulation and coding, scheduling, sector-switching,
channel supervision, control/hold etc.), MAC, and the effect of
mixing data and voice services. It will also discuss, in detail,
how 1xEV-DV exploits channel variation, channel quality feedback
and link adaptation to significantly increase the spectral efficiency.
The latter includes the design of enhanced reverse link high-speed
packet data service, MAC operation, rate control and power control.

Coding for Multiple Antenna Systems
Duration:
Half-Day, Monday Afternoon, Dec 1st
Instructors:
Prof. Ali Ghrayeb, ECE Dept.. Concordia University, Canada
Prof. Tolga M. Duman, Dept. Electrical Eng. , Arizona State University,
USA
Description:
Achieving reliable high-speed data transmission over wireless links is
a challenging task due to multipath fading and interference from other
users. The single most effective technique to combat such adverse effects
is to introduce diversity into the system. There are many different diversity
techniques including temporal, frequency, and spatial diversity. Furthermore,
different diversity techniques may be combined to enhance the performance
of the wireless system. Space-time coding, a new coding paradigm suitable
for multiple antenna systems, is a successful example that combines temporal
diversity (through channel coding) and spatial diversity (through multiple
transmit and receive antennas). This tutorial gives a complete overview
of the various emerging space-time coding techniques. These include space-time
trellis codes, space-time block codes, turbo codes, and concatenated codes
with iterative decoding , among others. The tutorial focuses on the construction
and performance analysis of such coding schemes over various wireless
channels. In addition, it addresses information theoretical limits for
multi antenna systems over wireless channels. Participants will also see
comparisons between these coding schemes in terms of performance and complexity.
In addition, several practical space-time coding architectures such as
BLAST and its variants will be described. Other practical issues such
as antenna selection at the transmitter and/or receiver and the effects
of sub-channel correlation on the system performance will also be considered.

In this tutorial, we give a comprehensive treatment of space-time signaling
under different channel state information (CSI) assumptions. We provide
a unified treatment of the different design approaches proposed in the
literature. We cut through the confusion of many mathematical aspects
of the problem and illustrate the connection between these aspects. After
reviewing the information theoretic foundations, multiple-input multiple-output
channels modeling, and the signal design criteria, we elaborate a unified
approach to the different space-time signaling schemes in the literature,
under different CSI scenarios (i.e., adaptive, coherent, non-coherent,
and differentially coherent). Similarly, we elaborate a unified approach
to the receiver architecture and the signal processing of the different
signaling schemes. Finally, we draw some conclusions and present some
problems for future research.

Ultra Wide Bandwidth Systems
Duration:
Half-Day, Monday Afternoon, Dec 1st
Instructors:
Prof. Moe Win, Laboratory for Information & Decision Systems,
MIT, USA
Prof. Andreas Molisch, Mitsubishi Electric Research Labs
Description:
Ultra-wide bandwidth (UWB) transmission systems have gained recent
interest in the scientific, commercial and military sectors. Wide
bandwidth provides fine delay resolution, making UWB a viable candidate
for communications in dense multipath environments, such as short-range
or indoor wireless communications. Currently, UWB transmission systems
are under consideration for high data rate communications and sensor
networks, because they allow low-cost production and reuse of (already
occupied) spectrum. UWB also has applications in military application
because it provides low probability of detection as well as anti-jam
capabilities. Interest in UWB systems has intensified recently due
to the ruling by the US Federal Communications Commission (FCC)
concerning UWB emission masks. This ruling opens the way for coexistence
with traditional and protected radio services and allows the potential
use of UWB transmission without allocated spectrum. Standardization
bodies (like IEEE 802.15) have started to develop standards for
UWB systems and companies are announcing products. In this tutorial,
we will give a technical overview that will allow the attendants
to distinguish between commercial hype and the true technical possibilities.

Mobile Internet and the Network Security
Duration:
Half-day, Monday Afternoon, Dec 1st
Instructor:
Prof. Abbas Jamalipour, University of Sydney, Australia
Description:
Wireless communication has already stabilized its unique and irreplaceable
position in personal telecommunications as well as in the global Internet
through cellular and wireless LAN infrastructures but still the issue
of quality of service and network security remain unresolved not only
in the mobile environment but also in the emerging heterogeneous networks.
In this tutorial, the Internet and mobile telecommunications security
will be addressed as a service quality element, different from the traditional
way of considering it as an isolated coding issue. This will put the security
as a network management component that has to be addressed through the
overall network architecture and system design. This includes the topic
of how the end-to-end service quality in the Internet could be guaranteed
when the network consists of wireless cellular systems of second- and
third-generation, IEEE 802.11 wireless LAN, and the wired LAN. The talk
will therefore provide a thorough description of obstacles in the way
of realization of quality of service and efficient traffic flow transportation
in the Internet, in which the security takes a major role. The Internet’s
quality of service techniques will be compared with those adopted in cellular
systems and challenges toward global harmonization to resolve the issue
will be revealed. Overview of the network security in cellular and Internet
will be provided. Architectural design, TCP/IP protocol enhancement and
mobility and traffic management required for the emerging secured mobile
Internet technology will be also discussed in this tutorial.

Smart Antennas for Wireless Systems
Duration:
Half-Day, Friday Afternoon, Dec 5th
Instructor:
Dr. Jack Winters, Motia, Inc.
Description:
Abstract: In this tutorial, we will discuss current and future wireless
systems, with emphasis on antenna technology and the improvement
that smart and adaptive antenna arrays can provide. We will first
discuss cellular systems, and describe standard cellular antennas,
smart antennas using fixed beams, and adaptive antennas for base
stations, as well as antenna technologies for handsets. We will
show the potential improvement that these antennas can provide,
including range extension, multipath diversity, interference suppression,
and capacity increase. We will describe in detail Multiple-Input-Multiple-Output
(MIMO) techniques, whereby multiple antennas are used both at the
receiver and transmitter. We will show how these MIMO techniques
are of great importance due to the fact that they have the potential,
with M transmit and receive antennas, to increase the data rate
M-fold without any increase in bandwidth or total transmit power.
The issues involved in incorporating these antennas into wireless
systems, including 2nd generation (CDMA, GSM, and IS-136), 3rd generation
(WCDMA and EDGE), and future (OFDM?) cellular systems, in different
environments, such as rural, suburban, and urban areas, as well
as indoors, will be described in detail. We will describe the evolution
to high-speed data mobile wireless systems, with data rates in excess
of 10 Mbps. We also describe the extension of wireless local area
networks using 802.11b/a/g, UltraWideBand (UWB), and cellular systems
(WCDMA), to provide high-speed ubiquitous access. Smart antennas
are shown as a key technology to provide the needed enhancements
of range extension, interference suppression, and capacity increase.
Theoretical, computer simulation, experimental, and field trial
results will be presented. This tutorial should provide a basic
understanding of the antenna technology options and their potential
in wireless systems.

Half-Day, Friday Morning, Dec 5th
Instructors:
Prof. William E. Ryan, The University of Arizona, USA
Prof. Bane Vasic, The University of Arizona, USA
Description:
Low-density parity-check (LDPC) codes are a class of linear block codes
for error-control on unreliable channels which are capable of near-capacity
performance. They are naturally described via a so-called Tanner graph
and have an easily understood iterative decoding algorithm. The purpose
of this tutorial is to teach the participants how to design, encode, and
decode LDPC codes. Code designs will involve probabilistic techniques,
techniques based on finite geometries, and techniques based on combinatorics.
Participants will learn about the performance of LDPC codes on standard
channels and their applicability to data transmission and data storage.
They will also see comparisons to turbo codes in terms of performance
and complexity.

Multiuser in Multicarrier Systems for Wireless Communications
Duration:
Half-Day, Monday Afternoon, Dec 1st
Instructor:
Prof. Y. Bar-Ness, New Jersey Institute of Technology, USA
Description:
There was a recent emphasis on using multi-carrier systems, in wireless
communications, as in for example IEEE 802.11a in the US and Hyperlan2
in Europe. OFDM modulation; the principle of data transmission for these
systems, has been shown to have many advantages in multi-path fading environments,
which wireless communications regularly face with. This is certainly not
without many problems that the system designer has to cope with. Probably
more than in wire-line systems, multi-user interference is an important
impairment that requires cancellation. In this tutorial we will detail
the principles of DAB, DVB and WLAN with emphasis on their related standards.
Different multi-users-multi-carrier schemes will be presented. Methods
for inter-user interference cancellation will be discussed. Some adaptive
de-correlating based algorithms will be included. Inter-carrier interference
is another problem, wireless multi-carrier systems are faced with. We
will present some ideas for handling such impurities. Finally we will
suggest and analyze different methods for multi-rate transmission in multi-carrier
systems and suggest avenues for canceling interference that these schemes
may cause.

Turbo-Like Codes: Analysis, Design, Iterative Decoding, and Applications
Duration:
Full-Day, Monday, Dec 1st
Instructor:
Prof. Sergio Benedetto, Politecnico di Torino, Italy
Description:
Turbo-like codes are concatenated codes (in parallel or serially) formed
by two simple convolutional encoders separated by an interleaver. They
have astonishing performance close to the Shannon limits, yet enable simple
decoding with complexity comparable to that of decoding the simple constituent
codes. After their invention in 1993, the so-called "turbo principle"
has been applied to such fields as equalization, multiuser detection,
and synchronization. This tutorial provides an understanding of the principles
governing the codes behavior, analytical tools to evaluate performance,
design rules for both the constituent codes and the interleaver, explanation
of the maximum-a-posteriori algorithms which form the core of the iterative
decoding algorithms, extensive analytical and simulation results, a comparative
analysis of the implementation complexity, an outline of parallel hardware
architectures for high-speed implementation, and a number of important
applications like third-generation wireless communications, digital video
broadcasting and deep-space communications.

Applications of the Viterbi Algorithm or How I learned to love the Trellis
Duration:
Half-Day, Friday Afternoon, Dec 5th
Instructor:
Dr. Bernard Sklar, Communications Engineering Services
Description:
The main goal of this tutorial is to show how the Viterbi algorithm works,
in a very intuitive way. The presentation will touch on several applications
of the algorithm, such as its use in decoding convolutional codes. However,
the emphasis of the tutorial will be to show how the algorithm works when
used for detection and equalization of signals. The equalization application
provides much insight into the process. Many equalizing techniques use
filters to modify the shape of received distorted pulses, and thereby
compensate for the non-ideal properties of the channel. The operation
of a Viterbi equalizer is quite dif-ferent. Distorted waveforms are not
reshaped or directly modified. Instead the mitigating technique provides
for the receiver to "adjust itself" in such a way that it can
better deal with the distorted waveforms.

Multimedia Security Technologies for Digital Rights Management
Duration:
Half-day, Monday Morning, Dec 1st
Instructors:
Prof. Deepa Kundur , Texas A&M University, USA
Dr. Ching-Yung Lin, IBM T. J. Watson Research Center, USA
Dr. Heather Yu, Panasonic Information and Networking Technologies
Laboratory, USA
Description:
Modern advancements in communication infrastructure, signal processing,
and digital storage technologies have enabled pervasive digital
media distribution; digital distribution allows the introduction
of flexible, cost-effective business models that are advantageous
for multimedia commerce transactions. The digital nature of the
information also allows individuals to manipulate, duplicate or
access information beyond the terms and conditions agreed upon in
a given transaction. The rapid adoption of high bandwidth connections
and peer-to-peer networks are accelerating this process faster than
ever before. This requires secure e-commerce systems that will allow
convenient use of digital content while equitably compensating members
of the information distribution chain such as content creators and
providers. A critical component of such secure e-commerce system
is digital rights management (DRM). DRM is the digital management
of user rights to allow reliable and secure distribution of digital
content through various networks. It involves linking specific user
rights to media in order to control viewing, duplication, and access
among other operations. Ideally, a DRM system balances information
protection, usability, and cost to provide a beneficial environment
for all parties; this includes expanded functionality, cost effectiveness
and new marketing opportunities. The challenge is to engineer secure
systems for an environment of dynamic applications and standards
in which appropriate business models and consumer expectations are
only now being identified. In this tutorial, we intend to present
topics of both practical and theoretical interest by providing the
participant with a comprehensive coverage of theoretical foundation
of security technologies for DRM, a broad overview of the increasingly
important applications of these technologies for DRM in multimedia
communications, and an in-depth survey of the state-of-the-art DRM
systems and the underlying technologies in order to identify trends
in DRM system evolution and to provide a good starting point for
individuals entering this active research area. The tutorial includes
three lectures: (1) Introduction to DRM: fundamental techniques
and technologies, (2) Standards, state-of-the-art systems, legal
issues for DRM, (3) Emerging technologies and applications.

Internet Traffic Monitoring and Analysis: Methods and Applications
Duration:
Half-Day, Friday Morning, Dec 5th
Instructor:
Prof. James Won-Ki Hong, Dept. of Computer Science and Eng., POSTECH,
Korea
Description:
Multi-gigabit networks are becoming common today in Internet service providers
(ISP) and enterprise networks. The bandwidth of ISP's backbone networks
is evolving from OC-48 (2.5Gbps) to OC-192 (10Gbps) to support rapidly
increasing Internet traffic. Also, enterprise networks are evolving from
100-Mbps or 1-Gbps to multi-gigabit networks. Further, the types of traffic
on these networks are changing from simple text and image based traffic
to more sophisticated and higher volume traffic (such as streaming rich
media, voice and peer-to-peer). Monitoring and analyzing such high-speed,
high-volume and complex network traffic is needed, but it lies beyond
the boundaries of most traditional monitoring systems. Various application
areas are requiring information generated from such traffic monitoring
and analysis. For example, such information can be used for 1) usage-based
billing, 2) denial-of-service (DOS) attack analysis, 3) network usage
analysis, 4) network capacity planning, 5) customer relationship management,
and so on. Many of these applications are critical to the business, operations
and management of ISPs and enterprises. This tutorial will present the
techniques involved in capturing and examining packets, generating and
storing flows, and analyzing them for various purposes and applications.
Active and passive packet monitoring techniques and tools are compared
and discussed. Monitoring and analysis tools such Cisco NetFlow, cflowd,
argus, and NG-Mon are examined. Application areas of such monitoring and
analysis tools will also be explored.

Pervasive Networking Infrastructures and Protocols
Duration:
Half-Day, Monday Morning, Dec 1st
Instructors:
Dr. Amitava Mukherjee, School of Computer Science and Engineering, UNSW,
Sydney, Australia
Dr. Debashis Saha, Indian Institute of Management Calcutta, India
Description:
We are moving towards a world of pervasive computing in which users can
access and manipulate information from anywhere at anytime, i.e., anytime/anywhere
any device any network any data. Computing devices and networks are becoming
ubiquitous. In this new world, computing will no longer be tethered to
desktops: users will become increasingly mobile. As users move across
environments, they will desire to remain connected all along so that they
can continue to access a dynamic range of applications and software services.
The terms, such as pervasive, invisible, calm, anytime/anywhere, wearable,
augmented reality, information appliances, may evoke a more symbiotic
relationship between humans and their environment. We can view this as
yet another paradigm shift in the relationship between humans and computers.
Human-Centered: What can and should we expect for human interaction within
a smart environment? Technology-Centered: What new requirements do smart
environments place on technology infrastructure, specifically networking
infrastructure? What new advances in programming or system construction
must accompany this paradigm shift? In the context of human-computer interaction
(HCI), a smart pervasive computing environment is one that adapts to the
needs of the information consumer, in terms of input/output capabilities,
as he/she moves and accesses information in a dynamically changing environment.
So what is needed for making pervasive computing a huge success is a solid
pervasive networking infrastructure that ties different sets of smart
nodes together, allowing them to communicate with one another to provide
ubiquitous computing services to users. There are several characteristics
of a pervasive networking environment that provide challenging research
issues to researchers from the industries and the academics.

Multimedia Transmission over WLANs using Cross Layer Design - Challenges,
Principles and Standards
Duration:
Half-Day, Friday Afternoon, Dec 5th
Instructors:
Prof. Mihaela van der Schaar, University of California Davis, USA
Dr. N. Sai Shankar, Philips Research, USA
Description:
Multimedia has become a major driving force behind today's information
technology. However, to achieve a high level of acceptability and proliferation
of multimedia over wireless LANs (WLANs), challenges such as mobility,
increasing traffic density, time varying channel conditions, receiver
heterogeneity etc., need to be addressed. Currently, each layer (PHY,
MAC, Transport, Application) in the OSI stack provides a separate solution
to these challenges by providing its own optimized adaptation and protection
mechanisms. Cross-layer design emerges as a promising methodology for
providing QoS guarantees for multimedia streams over WLANs. This tutorial
provides a comprehensive description of the challenges, principles and
standards that are important for cross-layer optimized transmission of
multimedia over WLANs. We provide an overview of emerging technologies
such as IEEE 802.11e that adds QoS features and multimedia support to
the existing 802.11a/b/g wireless standards and explain how to use its
features for improved multimedia delivery over WLANs. Moreover, we present
the various aspects of QoS implementation at the transport and application
layers. We discuss different packetization, packet classification, packet
filtering and scheduling mechanisms for delivery of multimedia coded content,
as well as error resilient coding methods present in existing or upcoming
multimedia compression standards. We will conclude the tutorial with a
demonstration of a cross-layer optimized wireless video transmission system.

Building Scalable Ad-Hoc Collaboration Networks
Duration:
Half-Day, Friday Morning, Dec 5th
Instructors:
Dr. Krishna Kant, Intel Corporation, USA
Mr. Vijay Tewari, Intel Corporation, USA
Dr. Ravi Iyer, Intel Corporation, USA
Description:
Interest in ad-hoc collaboration networks has resurged due to several
technological developments including the emergence of the peer-to-peer
computing paradigm, explosive growth of IEEE 802.11 based wireless networking,
vehicular networks approaching reality, etc. As the capabilities of mobile
devices and wireless networking technology/infrastructure expand, ad-hoc
networks are expected to play a dominant role in almost every aspect of
daily life. The tutorial shall start with a brief introduction to mobile
ad-hoc computing and touch upon issues like service architectures, usage
models for collaboration, capability/heterogeneity issues, etc. The tutorial
will also introduce a number of peer-to-peer computing applications and
the infrastructure necessary for arbitrary P2P computing on a WAN scale
including some examples such as Legion, OGSA, etc. The tutorial will then
address the issues that limit WAN level collaboration, including NATs/Firewalls,
addressing issues, low-latency and scalable location services, etc. The
tutorial will present a common set of requirements for collaborative ad-hoc
computing applications and show how they can be mapped to a middleware
service stack. The last part of the tutorial shall briefly discuss the
performance issues related to dynamic ad-hoc networks including analytic
and simulation modeling using random graph models, sensitivity of performance
to various information location and caching options, and HW/SW features
for enhancing performance in a highly dynamic environments.
