Vice President and Chief Scientist, Flarion


Recent experience in a deployment of Flash OFDM in the Raleigh area by Nextel ha s shown that Flash OFDM offers the best technological solution for mobile wirele ss data. The transition from wireless voice to wireless data necessitates a rec onsideration of both system networking design and the wireless channel. This ta lk will focus on a key enabling property of OFDM, namely the granularity is supp orts, and how it can be exploited for mobile wireless data. Several examples wi ll be given, including a description of the recently announced Flex-band system.


Dr. Richardson is responsible for signal modulation and coding for Flarion's FLA SH-OFDM® system. He joined Flarion in June 2000. Prior to that, beginning in 1990, he was a member of the Mathematical Sciences Research Center in Bell Laboratories.

His current main interest is iterative coding methods, especially Low-Density Parity-Check codes. He has published also in other areas of signal processing (multiple antennas, computer vision, and neural networks) and in mathematics, particularly in geometry. He was co-winner of the information theory society best paper award in 2001 and is currently an associate editor of the IEEE Transactions on Information theory. He is inventor on more than 20 patents granted or submitted.

He received a Ph.D. in Electrical Engineering from the Massachusetts Institute of Technology in 1990 after leaving the University of Toronto with a Bachelor's and a Master's degree (1986), also in Engineering.
