Abstract
The changes in technology for wireless communications have been dramatic from the 1960's until today. The use of those changes has dramatically increased information flow and has had a worldwide effect on the economy. Mathematical research and entrepreneurial activities by faculty and former students at Purdue University have had a significant impact on these technological developments. A partial description of this impact using pictures and sketches is the goal of the presentation.
Biography
James S. Lehnert received the B.S. (Highest Honors), M.S., and Ph.D. degrees in electrical engineering from the University of Illinois at Urbana-Champaign in 1978, 1981, and 1984, respectively. From 1978 to 1984, he was a research assistant at the Coordinated Science Laboratory, University of Illinois, Urbana, Illinois. Dr. Lehnert was a University of Illinois Fellow from 1978 to 1979 and an IBM Pre-Doctoral Fellow from 1982 to 1984. He has held summer positions at Motorola Communications, Schaumburg, Illinois, in the Data Systems Research Laboratory, and Harris Corporation, Melbourne, Florida, in the Advanced Technology Department. He is currently a Professor in the School of Electrical and Computer Engineering at Purdue University, and was selected as a Purdue University Faculty Scholar in 2003. He received the IEEE Military Communications Conference (MILCOM) Award for (Lifetime) Technical Achievement in 2009 and was identified during 2000-2010 by Thomson Reuters as a Highly Cited Researcher across the previous three decades. Dr. Lehnert has served as Editor for Spread Spectrum for the IEEE Transactions on Communications and as Guest Editor for the IEEE Journal on Selected Areas in Communications. He is a Fellow of the IEEE for contributions to the theory and practice of spread-spectrum multiple-access communications. Recent research interests include spectrum management, biological communications, code-division multiple-access (CDMA) for wireless communication networks, channel estimation, interference excision, and signal processing in software programmable radios.
