                                    Abstract

Signal fading has been an enduring problem since the advent of modern
communication systems and most recently has received considerable
attention relative to the wireless communication channel. Literally
hundreds of authors over the past forty years have contributed to the
literature dealing with this problem in one form or another. A large
number of these contributions fall into the category of performance
evaluation of systems impaired by this phenomenon. Traditional analytical
solutions to this problem have, in many instances, taken the form of
complicated expressions that provide little or no insight into the
dependency of the system behavior on the various system parameters that
characterize it. In other cases, closed-form solutions were not possible
at all.

Using alternative representations of such classic mathematical functions
as the Gaussian probability integral (Q-function), Marcum Q-function, and
incomplete gamma function, a unified approach to evaluating the
performance of digital communication systems in the presence of fading
has been recently proposed. Aside from allowing all previous results to
be placed within a common framework, this approach has the additional
advantages of: 1) simplifying the analysis and computation of existing
results and 2) allowing one to obtain closed-form results for special
cases that until now resisted solution. The approach applies to a broad
class of signaling/detection types and fading channel models typical of
practical communication systems and in all cases the resulting
performance expressions obtained can be readily evaluated numerically.

Since the introduction of the above approach, other unifying-type methods
have been proposed based on Parseval's theorem and numerical
approximation of the inverse Laplace transform. The talk will review and
discuss these various performance analysis approaches in the context of
their application to the wireless communication channel. Although the
focus of the talk will be on single input-multiple output systems, the
ability to extend the analysis approaches to multiple input-multiple
output (MIMO) systems that employ space-time coding (STC) has also been
demonstrated and will be mentioned.


                          Biography of Marvin K. Simon

Dr. Marvin K. Simon is a Principal Scientist at the Jet Propulsion
Laboratory, California Institute of Technology, Pasadena, California
where for the last 34 years he has performed research as applied to the
design of NASA's deep-space and near-earth missions and which has
resulted in the issuance of 9 patents and 23 NASA Tech Briefs. Dr. Simon
is known as an internationally acclaimed authority on the subject of
digital communications with particular emphasis in the disciplines of
modulation and demodulation, synchronization techniques for space,
satellite and radio communications, trellis-coded modulation, spread
spectrum and multiple access communications, and communication over
fading channels. In the past, Dr. Simon also held a joint appointment
with the Electrical Engineering Department at Caltech where for 6 years
he was responsible for teaching the first year graduate level
three-quarter sequence of courses on random processes and digital
communications. He is currently on Research Leave in the Department of
Electrical Engineering at the University of California, Los Angeles.

He has published over 170 papers on the above subjects and is author of
numerous textbooks including, Telecommunication Systems Engineering
(Prentice-Hall, 1973 and Dover Press, 1991), Phase-Locked Loops and Their
Application (IEEE Press, 1978), Spread Spectrum Communications, Vols. I,
II, and III (Computer Science Press, 1984 and McGraw-Hill, 1994), An
Introduction to Trellis Coded Modulation with Applications (MacMillan,
1991), Digital Communication Techniques: Vol. I (Prentice-Hall, 1994),
Digital Communication Over Fading Channels: A Unified Approach to
Performance Analysis (John Wiley & Sons, 2000) and Bandwidth Efficient
Modulation for Deep Space Applications (John Wiley & Sons, 2002) and
Probability Distributions Involving Gaussian Random Variables: A Handbook
for Engineers and Scientists (Kluwer Academic Publishers, 2002). His work
has also appeared in the textbook Deep Space Telecommunication Systems
Engineering (Plenum Press, 1984), Mobile Communications Handbook (CRC
Press, 1995), Communications Handbook (CRC Press, 1997) and the
Electrical Engineering Handbook (CRC Press, 1997). He is the co-recipient
of the 1988 Prize Paper Award in Communications of the IEEE Transactions
on Vehicular Technology for his work on trellis coded differential
detection systems and also the 1999 Prize Paper of the IEEE Vehicular
Technology Conference for his work on switched diversity. He is a Fellow
of the IEEE, Fellow of the IAE, and has been awarded the NASA Exceptional
Service Medal, NASA Exception Engineering Achievement Medal, IEEE Edwin
H. Armstrong Achievement Award and most recently the IEEE Third
Millennium Medal all in recognition of outstanding contributions to the
field of digital communications and leadership in advancing this
discipline.
