Biographical sketch


Dr. Bahai received his MS degree from Imperial College, University of London in 1988 and Ph.D. degree from University of California at Berkeley in 1993, all in Electrical Engineering. From 1992 to 1994 he worked as a member of technical staff in the wireless communications division of TCSI. He joined AT&T Bell Laboratories in 1994 where he was Technical Manager of Wireless Communication Group in Advanced Communications Technology Labs until 1997. He was involved in research and design of several wireless standards such as PDC, IS-95, GSM, and IS-136 terminals and Base stations, as well as ADSL and Cable modems. He is one of the inventors of Multi-carrier CDMA (OFDM) concept and proposed the technology for high speed wireless data systems. He was the co-founder and Chief Technical Officer of ALGOREX Inc. and currently is a Fellow and the Chief Technologist of National Semiconductor He is an adjunct/consulting professor at Stanford University and UC Berkeley. His research interest includes adaptive signal processing and communication theory. He is the author of more than 50 papers and reports and his book on "Multi-carrier Digital Communications" is published by Kluwer/Plenum. Dr. Bahai holds five patents in Communications and Signal Processing field and served as an editor of IEEE Communication Letters.
