Dr. Scholtz, working on missile radar signal processing problems, remained part-time at Hughes Aircraft Co. until 1978. In 1963, Dr. Scholtz joined the faculty of the University of Southern California, where he is now the Fred H. Cole Professor of Engineering. From 1984 through 1989, he served as Director of USC's Communication Sciences Institute, and from 1994 to 2000 he was Chairman of the Electrical Engineering Systems Department. In 1996, Dr. Scholtz formed the Ultrawideband Radio Laboratory (UltRa Lab) to provide facilities for the design and test of impulse radio systems and other novel high-bandwidth high-data-rate wireless mobile communication links. He has served as a consultant to several corporations and government agencies.
His research interests include communication theory, synchronization, signal design, coding, adaptive processing, and pseudonoise generation, and their application to communications and radar systems. He has co-authored the books Spread Spectrum Communications, the Spread Spectrum Communications Handbook, and Basic Concepts in Information Theory and Coding.
Dr. Scholtz is a Fellow of the IEEE and a member of the National Academy of Engineering. He has received many awards for his work, including the 1984 Donald G. Fink Prize, 1992 Senior Award of the IEEE Signal Processing Society, the 2003 S. A. Schelkunoff Prize from the IEEE Antennas and Propagation Society. Dr. Scholtz is a co-recipient of the 2006 Eric E. Sumner Medal from the IEEE "for pioneering contributions to ultra-wide band communications science and technology."
