THE CENTER FOR COMMUNICATIONS AND SIGNAL PROCESSING RESEARCH and THE NORTH JERSEY CHAPTERS OF THE IEEE COMSOC AND SP SOCIETIES Present "CHANNEL CODING FOR WIRELESS COMMUNICATIONS" by Dr. Branko Jelicic AT&T Bell Labs, Middletown, NJ. WHEN: Wednesday, March 6, 1996, 6:45p.m. (Refreshments at 6:15p.m.) WHERE: Room 202, Electrical and Computer Engineering Center New Jersey Institute of Technology About the Talk: With the recent developments in mobile and portable wireless communications the problem of code design for reliable, high-speed data transmission over corresponding physical channels is of considerable current interest. The aim of this presentation is to first give an insight into the basic code design principles for channel models that arise in the wireless communications. It will be shown that there is an equivalent (in most cases) between coding and so called time diversity (sending the same message several times). Subsequently, an array of coding schemes available today will be presented, with the aim of matching a certain channel model to a particular channel coding technique. Two new coding schemes will be presented. The first one, coordinate interleaved QAM-Trellis Coded Modulation is aimed at future mobile transmission systems that will require delivery at higher information rates with greater power efficiency as compared to currently used PSK constellations. The second coding scheme aimed at packetized transmission of information requiring short end-to-end delay a nd bit-error-rates lower then 10^(-6) will present a new algorithm that enables soft decision decoding of a large class of block codes with performance level close to maximum likelihood procedure, at a fraction of the complexity of the latter. Some directions for future research in the area will be given. About the Speaker: Dr. Branko Jelicic was born in Novi Sad, Yugoslavia, in 1965. He received the Dipl. Ing. degree in electrical engineering from the University of Novi Sad, Yugoslavia, in 1990, and the M.S. and PhD degrees from the University of Pennsylvania, Philadelphia, PA, in 1993, and 1995, respectively. From 1990 to 1991 he was a Teaching Assistant at the University of Novi Sad. From 1991 he has been a Research and the Teaching Assistant at the University of Pennsylvania, at Electrical Engineering and Mathematics departments. During the 1995 Spring semester he was a research scientist at the University of Texas at San Antonio. In the summer of 1993 he worked for AT&T Bell Labs., Murray Hill, NJ; and in the summer of 1994 for AT&T Bell Labs., Middletown, NJ. Since August 1995 he has been with AT&T Bell Labs. Advanced Multimedia Communications department in Middletown, NJ. His research interests are in the areas of communication theory and signal processing.
