Future Directions in Adaptive Signal Processing
W. Kenneth Jenkins



In the late 1950's when Widrow and Hoff of Stanford University introduced the Least Mean Squares (LMS) adaptive filter, and shortly thereafter when Robert Lucky of AT&T proposed the first adaptive equalizer based on similar principles, the integrated circuit technology of the day was not sufficiently advanced for practical implementations of these novel concepts. However, during the last three decades rapid advancements in adaptive signal processing theory and digital integrated circuit technologies have allowed adaptive techniques to assume key roles in digital processing associated with telephone communications, adaptive control systems, digital coding of speech, and digital processing of video signals. This talk will review current practices and discuss future directions of adaptive signal processing, with particular attention devoted to certain advanced topics that are not currently used in practice, but which are potentially impor tant concepts that now exist scattered through the research literature. These advanced topics include improved performance adaptive algorithms for 1-D adaptive filters, architectures and algorithms for 2-D adaptive filters, the introduction and development of a recently researched concept called adaptive fault tolerance, and a review of some recent results on adaptive polynomial filters.

W. Kenneth Jenkins received the B.S.E.E. degree from Lehigh University, Bethlehem, PA, in 1969, and the M.S.E.E. and Ph.D. degrees from Purdue University, West Lafayette, IN, in 1971 and 1974, respec tively. From 1974 to 1977 he was a Research Scientist Associate in the Communication Sciences Laboratory at the Lockheed Research Laboratory, Palo Alto, CA. In 1977 he joined the faculty at the University of Illinois at Urbana-Champaign where he is currently Professor in the Electrical and Computer Engineering Depart ment and the Director of the Coordinated Science Laboratory. His current interests include digital filtering, signal processing algorithms, multidimensional array process ing, computer imaging, one and two dimensional adaptive digital filtering, and VLSI architectures for signal processing. He is a past President (1985) of the IEEE CAS Society, and a Fellow of the IEEE. In 1990 Dr. Jenkins was awarded the Distinguished Service Award of the IEEE Circuits and Systems Society for important and sustained professional contributions to the Society over many years. During the fall of 1995 he spent a sabbatical leave at the University of York in the UK, where he held the position of Honorary Visiting Professor.

How to Wake Up Your Creative Genius!
William C. Boon

Bill Boon has been teaching at the university since 1973. He has written a book recently published "Nature's Heartland" covering native plants of the Midwest region. Bill's presence is well known in Iowa and a few of the surrounding states because of a large class on creativity called "Creativity, Design and Society" he teaches both fall and spring semesters that has produced cardboard boat races at Veishea, cardboard shelters for the homeless, water balloon launchers (where he was the target), and a minor miracle that had students walking on water. Many of these projects were given publicity by both television and newspaper coverage.

William C. Boon is a Professor in Landscape Architecture at Iowa State University. He holds three degrees: a B.S. in Agronomy and a B.S. in Landscape Architecture from Kansas state University, and a Masters in Landscape Architecture from Iowa State University.

Giant Magnetoresistance - A Paradigm Shift for Magnetics
Jim Daughton, NVE
In the second half of the 20th century there has been a rapid shift toward high density, lower power electron ics. The field of magnetism and magnetic materials has been affected by and is part of this shift. Magneto -resistance is a more useful phenomenon than is magneto-inductance for applications where miniaturization is critical. The discovery of Giant Magneto-Resistance (GMR) in 1988 has not only accelerated the use of magneto-resistance in this century, but it has also stimulated new research in related phenomena which are very promising for applications in the first part of the 21st century.


Dr. James M. Daughton, President NVE - In 1989 Dr. Daughton founded NVE, a company based on integrat ing GMR materials with integrated circuits to make innovative products. Previously, Dr. Daughton spent over 15 years at Honeywell Inc as an executive and 10 years at IBM as a Senior Engineer. Dr. Daughton received his BS, MS, and PhD degrees in EE in 1959, 1961, and 1963, respectively, from Iowa State University. He is a fellow of the IEEE and a member of the Magnetics Society.
