Abstract: Have you ever thought about how you got to your current state and what events and interactions shaped your career path? This talk describes concepts and events related to ultrawideband radio, when/how they entered into the considerations of this engineer, and how they led to formation of the UltRa Lab at USC. Academic training, technical exposure to radar systems, spread-spectrum techniques, and the theory of their operation certainly provide one possible knowledge base for the study of UWB communications. More interesting are the less predictable social conversations, cold-approach phone calls, and small decisions that eventually influenced major changes in the course of this engineer's technical research toward ultrawideband radio. This retrospective concludes with a survey of the works of students who took advantage of the UltRa Lab's research environment. Bio: Robert A. Scholtz is a Distinguished Alumnus of the University of Cincinnati, where, as a Sheffield Scholar, he received the Degree in Electrical Engineer in 1958. He was a Hughes Masters and Doctoral Fellow while obtaining his MS and PhD degrees in Electrical Engineering from USC in 1960 and Stanford University in 1964 respectively. 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."
