Abstract
Quasi-Static (or very slow) fading channels (QSFC) occur
in a variety of applications including TDMA cellular systems and
indoor wireless local area networks. In this talk, it will be
first demonstrated that coded communications systems can exhibit
strange behavior on the QSFC. Classical wisdom on the design of
good error correction codes can lead to very poor designs for the
QSFC. Part of the reason for this is the inadequacy of Union-Chernoff
bounding techniques when applied in the QSFC. Hence, we develop
alternative approaches to bound the performance of coded communication
systems over QSFC. The resulting improved performance bounds also
give some initial insight into how one might design better codes
for the QSFC. These performance evaluation tools will be applied
not only to single antenna systems, but also to systems with
multiple transmit antennae and/or multiple receive antennae. These
new results will also lend some insight into the performance of
turbo space-time coded systems.
Biography
Scott Miller was born in Los Angeles California in 1963.
He received the B.S., M. S., and Ph. D. degrees in Electrical
Engineering from the University of California at San Diego (UCSD)
in 1985, 1986, and 1988 respectively. He then joined the Department
of Electrical and Computer Engineering at the University of Florida,
where he was an Assistant Professor from 1988 through 1993 and an
Associate Professor from 1993 through 1998. In August 1998 he
joined the Electrical Engineering Department at Texas A&M University
where he is currently a Full Professor. He has also held visiting
positions at Motorola Inc., University of Utah and UCSD. His
current research interests are in the area of wireless communications
with a special emphasis on CDMA systems. He was an Editor
the IEEE Transactions on Communications from 1995 through 1998 and
from 2000-present.
