NEW SIGNAL PROCESSING TECHNIQUES FOR WIRELESS COMMUNICATIONS

Gregory W. Wornell
Department of Electrical Engineering and Computer Science
Massachusetts Institute of Technology

Signal processing has an increasingly important role to play in the development of future wireless modems. In this talk, I'll described ways in which efficient new signal processing techniques may be used to improve communication over fading channels. For single-user systems, I'll develop an attractive alternative to interleaving which I refer to as spread-response precoding. In the multiuser scenario, I'll discuss how spread-response precoding generalizes to a novel class of code-division multiple-access systems whose signature sets have a special structure that is markedly different from that in traditional systems. To keep the talk as accessible as possible (and bolster attendance), no special familiarity with wireless systems will be assumed.
