After graduating from Rice University in 1985, Dr. Hoffman joined the Space Communications Division of TRW, Inc., as a Systems Engineer. While working at TRW, he attended the University of Southern California on a TRW Fellowship and completed his Masters degree. In 1988 he left TRW and returned to graduate school in Minneapolis, MN. His dissertation topic was robust processing of microphone arrays for hearing aid applications. Since joining the UNL faculty in January of 1993 he has continued his signal processing work in microphone array processing and other real-time applications of signal processing.
Applications of Digital Signal Processing to sensor array problems such as a multiple microphone front ends for speech coders, including real-time implementation considerations. Other interests in communications include joint source/channel coding, data compression, and the application of sensor array signal processing techniques to the problem of acquiring and copying signals.
