Ph.D., Georgia Institute of Technology, 1999
Dr. Thomas (Tom) Pratt (Ph.D. Georgia Tech, 1999; MSEE Georgia Tech 1989, BSEE Notre Dame 1985) was hired as a Research Associate Professor at the University of Notre Dame where his research focus is on physical layer issues associated with wireless communications and sensor systems. Prior to his appointment at Notre Dame, Dr. Pratt was a Principal Research Engineer at the Georgia Tech Research Institute where he had conducted systems research associated with RF and communications systems for over 23 years. His work at GTRI involved theoretical studies, simulation, design and analysis, and the development and use of experimentation/demonstration systems for various PHY layer investigations. Examples include extensive RF systems development and testing at DoD test facilities, prototype development based upon software-defined radio technology, joint development of an FPGA-based implementation of real-time algorithms for WLAN detection in co-channel interference, and the development and demonstration of a dual phased array interference suppression system. While at GTRI, Dr. Pratt built-up and served as the Director of Georgia Tech�s Software Radio Laboratory and also led the development of a mobile-to-mobile MIMO test system and associated experimentation to collect and analyze dual-polarized and full-polarized channel data for wireless applications. He has experience with a number of wireless standards, including WLAN 802.11a/b/g, WiMax, GSM, and 3G (to varying degrees). He was coauthor on a best paper at ICC�08 (dealing with mobile-to-mobile channel modeling) and gave a keynote address on multiport architectures at the recent WAVE 2008 conference in Dearborn, MI. He holds a patent on signal processing for GSM receivers and has two patents pending associated with multi-port adaptive transmission and interference suppression algorithms respectively. He has authored or coauthored over 100 reports and publications and is a member of the IEEE.
Summary of Activities/Interests
Research Interests: Dr. Pratt has particular interest in multi-port and dual-polarized communications and sensing architectures and their application to detection, interference avoidance and suppression, sensing, and diversity and capacity enhancement. His recent research (at Notre Dame and/or at Georgia Tech) has included MIMO channel modeling associated with linear arrays and dual-polarized architectures, polarimetric sensing of communications signals, cosite interference suppression, distributed aperture processing concepts for MIMO radar, and adaptive transmission concepts for wireless systems.
