Don Hummels is an active researcher in the area of receiver design and nonlinear signal processing strategies. He has consulted for Central Florida Technical Services (Modem design for nonlinear satellite channels) the MIT Lincoln Laboratory (application of statistical pattern recognition for identification of targets from polarimetric radar images), and the Naval Undersea Warfare Center (Detection and identification of Underwater Acoustic Sources). He has worked closely with Fred Irons in the development of a computerized test system capable of characterizing nonlinear receiver components in the 10-1000 MHz region. Initial projects have concentrated on the problem of dynamic compensation of high speed (10-500 MHz) analog to digital converters for use near the front-end of digitally-implemented receivers.
