Spectrum Sharing, Cognitive Radio, and Spectrum Access Systems: Motivation, Concepts, and Selected Projects

Carl Dietrich, Ph.D.
Research Associate Professor
Bradley Department of Electrical and Computer Engineering, Virginia Tech

Nedderman Hall Room 112

Abstract: The U.S. government is moving toward a shared-spectrum approach to regulating many radio frequency bands, with the goal of stimulating the economy through enhanced wireless service. The President’s Council of Advisors on Science and Technology (PCAST) recommended in a 2012 report that the Federal government initiate this process by opening a gigahertz of spectrum that had been allocated exclusively for societal benefits, and recent spectrum auction results indicate a value of the radio spectrum that is generally consistent with this projection. This talk will review the motivation for sharing radio frequency bands as well as two technologies that can assist in this process: cognitive radio and spectrum access systems, and highlight some related research and educational efforts, with emphasis on ongoing projects at Virginia Tech.

Bio: Carl B. Dietrich earned Ph.D. and M.S. degrees from Virginia Tech and a B.S. degree from Texas A&M, all in electrical engineering. His research interests include spectrum sharing, cognitive radio, software defined radio, multi-antenna systems, and radio wave propagation. Dietrich has chaired the Wireless Innovation Forum’s Educational Special Interest Group and is an IEEE Senior Member and a member of IEEE Eta Kappa NU and ASEE. He is also a licensed professional engineer in Virginia.
