Tim Dyson is Lead Analyst in the Signal Processing Center of Excellence at the Government Communications Systems Division of Harris Corporation
He is responsible for developing innovative and implementation efficient digital communications algorithms for next generation military satellite communications application. His primary interests are in the physical layer processing for optimum coherent receivers, modulators and demodulators, amplifier linearization and efficient channelizers/synthesis techniques for multi-user communications channels.
From 2001 to 2004, he worked in space-based intercept and reconnaissance developing large instantaneous bandwidth digital receivers, signal detection and Bayesian classification methods. From 1999 to 2001 he developed super-linear, high-power amplifier methods including adaptive digital pre-distortion, Envelope Elimination and Restoration and LINC/Out-phasing residual AM compensation algorithms for 3G cellular Base Stations and handheld transmitters using LDMOS and JFET power transistors operating in saturated Class-B, Class F and Class E modes.
From 1986 to 1998 he worked on developing optimal and locally optimal non-Gaussian detectors for Sonar and direct conversion, wireless data transport systems for sub-carrier access in the commercial AM and FM Broadcast bands for US and European markets.
Tim has published a dozen articles in peer review journals and various International Conferences on Signal Processing, Communications and Surveillance, and delivered more than 50 invited technical presentations to US Government Agencies for Remote Sensing and Surveillance applications. He has been a reviewer for IEEE ASSP and Control Theory Transactions, the Signal Processing Journal and several classified US Government publications. Tim holds several US Patents for his designs for AM and FM Broadcast digital sub-carrier communications methods, efficient high-speed modulation and interative decoding. He is the recipient of the1988 Carl T. Humphreys Award for “Outstanding Professional Achievement” from Villanova University and was Adjunct Professor of Electrical Engineering at Villanova University from 1982 to 1998.
