Communications, Control, and Signal Processing Group: Adaptive filtering, array processing, wireless communications, blind equalization, and interference rejection. Professor Shynk joined the Department of Electrical and Computer Engineering in 1986 after receiving his Ph.D. degree from Stanford University. Previously, he was a Member of Technical Staff at AT&T Bell Laboratories in Holmdel, NJ. His research interests are in the general area of adaptive signal processing, with applications in communications and bioengineering. He has developed stochastic models for various adaptive systems to investigate their transient and steady-state properties. Currently, his research group is developing algorithms and receiver architectures for adaptive arrays that separate and demodulate cochannel sources in wireless communication systems. These algorithms employ a combination of training and "blind" adaptation to recover and track several sources, and generate estimates of their directions of arrival. The adaptive arrays provide a spatial processing capability that enhances conventional equalization techniques. Theoretical models have been developed to analyze the performance of the adaptive algorithms for a range of channel and signal conditions. Professor Shynk serves as an Associate Editor for the IEEE Transactions on Signal Processing, and was the Technical Program Chair for the 1992 International Joint Conference on Neural Networks in Baltimore. Prevously he was an Associate Editor for IEEE Signal Processing Letters and the International Journal of Adaptive Control and Signal Processing. He received the Engineering Distinguished Teaching Award in 1992, and a National Science Foundation Research Initiation Award in 1993.
