Steve C. Thompson

I am an electrical engineer working for Acorn Technologies in the San Diego area. My area of specialty is digital wireless communication systems. I also maintain some affiliation with the California Institute for Telecommunications and Information Technology (Calit2), part of the University of California, San Diego.

Research

My research interests are in the general area of digital communications. I'm particularly interested in the modulation format orthogonal frequency-division multiplexing (OFDM). Currently, I'm working on WiMAX and equalization. I also have my toe in the water de constant envelope OFDM. Besides these things, I'm interested in computer simulation techniques, wireless channel modeling, continuous phase modulation, and general communication theory.

Curriculum Vitae

My curriculum vitae, as of June 21, 2007, can be found here. (ps, tex, txt)

Education

In 1999, I received the Bachelor of Science degree in Electrical Engineering at Arizona State University, Tempe, AZ. In 2001, I received the MS degree in Electrical Engineering at the University of California, San Diego, where I've just recently completed my PhD work. My graduate advisors were John G. Proakis and James R. Zeidler.
