Abstract:      In this talk, we present various results on the effects
of noisy channel state information on the performance of various digital
communications systems. Our primary focus is on using the noisy
estimates for diversity combining, and we consider both single carrier
and multicarrier systems. Among the topics to be presented are
corrections to results in the literature that in some cases go back more
than 40 years. For example, it has been reported in the literature that
with a coherent BPSK system with multiple independent, identically
distributed, diversity branches, if the pilot channel is uncorrelated
with the data channel, then the bit-error rate varies inverse linearly
with average SNR. However, we show that the bit error rate equals 0.5,
independent of the number of diversity branches.


                                            

Speaker Bio:    Milstein received the B.E.E. degree from the City
College of New York in 1964, and the M.S. and Ph.D. degrees in
electrical engineering from the Polytechnic Institute of Brooklyn in
1966 and 1968, respectively. From 1968 to 1974, he was with the Space
and Communications Group of Hughes Aircraft Company, and from 1974 to
1976, he was a member of the Department of Electrical and Systems
Engineering, Rensselaer Polytechnic Institute, Troy, NY. Since 1976, he
has been with the Department of Electrical and Computer Engineering at
UC San Diego, where he is the Ericsson Professor of Wireless
Communications and former department chairman, working in the area of
digital communication theory with special emphasis on spread-spectrum
communication systems. He has also been a consultant to both government
and industry in the areas of radar and communications.

 

Milstein was an associate editor for communication theory for the IEEE
TRANSACTIONS ON COMMUNICATIONS, an associate editor for book reviews for
the IEEE TRANSACTIONS ON INFORMATION THEORY, an associate technical
editor for the IEEE Communications Magazine, and the editor-in-chief of
the IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS.  He was the vice
president for technical affairs in 1990 and 1991 of the IEEE
Communications Society, and is a former chair of the IEEE Fellows
selection committee. He is a recipient of the 1998 Military
Communications Conference Long Term Technical Achievement Award, an
Academic Senate 1999 UCSD Distinguished Teaching Award, an IEEE Third
Millennium Medal in 2000, the 2000 IEEE Communication Society Armstrong
Technical Achievement Award, and various prize paper awards, including
the 2002 MILCOM Fred Ellersick Award.
