Recent spectrum measurement campaigns have compellingly demonstrated that the existing static spectrum allocation policies result in inefficient use of the scarce radio spectrum. This observation, coupled with the inevitable trend towards proliferation of wireless communication devices and networks, necessitates new methodologies for efficient use of the available radio spectrum. Cognitive wireless systems in which the communication devices can dynamically sense and adapt to their local radio environment have emerged as a promising approach for addressing this challenge. A wide variety of new research directions have emerged recently to realize the vision of cognitive wireless networks, including spectrum sensing techniques, approaches for dynamic and opportunistic spectrum access, waveform-agile communications, and reconfigurable RF front ends. This first session provides a snapshot of the state-of-the-art theory and techniques for sensing, access and management of the limited radio spectrum in a variety of scenarios ranging from wireless local area networks to mobile tactical communication environments. The second companion session (US-W-F) presents recent results on experimental approaches and case studies in the development of cognitive wireless systems.
Akbar M. Sayeed received the B.S. degree from the University of Wisconsin-Madison in 1991, and the M.S. and Ph.D. degrees from the University of Illinois at Urbana-Champaign in 1993 and 1996, all in Electrical Engineering. He was a postdoctoral fellow at Rice University from 1996 to 1997 and he has been with the University of Wisconsin-Madison since 1997 where he is currently Associate Professor of Electrical and Computer Engineering. His current research interests include wireless communications, statistical signal processing, multi-dimensional communication theory, information theory, and applications in wireless networks. Dr. Sayeed is a recipient of the Robert T. Chien Memorial Award (1996) for his doctoral work at Illinois, the NSF CAREER Award (1999), the ONR Young Investigator Award (2001), and the UW Grainger Junior Faculty Fellowship (2003). Dr. Sayeed is a Senior Member of the IEEE, served as an Associate Editor for the IEEE Signal Processing Letters from 1999 to 2002, and as a Guest Editor for a special issue of the IEEE Journal on Selected Areas in Communications on sensor networks in 2005. Babak Daneshrad obtained the B.Eng. and M.Eng. degrees from McGill University, Montreal, Canada in 1986 and 1988 respectively, with emphasis on communication systems. He obtained the Ph.D. degree from UCLA in 1993 with emphasis on integrated circuits and systems. From 1993 to June 1996 Prof. Daneshrad was a member of the technical staff with the Wireless Communications Systems Research Dept. of AT&T Bell Laboratories where he was involved in the design and implementation of systems for high-speed indoor and outdoor wireless data communications. As a consultant with the TI DSP R&D center from June to Sept. 1996, he was involved with the design of systems for 100Base-T Ethernet. Between 1990 and 1993 he held positions as a consulting engineer in the areas of digital VLSI ASIC design and communication system design with PairGain Technologies, LinCom Corporation, Level One Communications, and Raytheon Semiconductors. In Sept. 1996 Dr. Daneshrad joined the Electrical Engineering Department at the University of California, Los Angeles (UCLA), where he is conducting research in the areas of low power VLSI circuits for communications and signal processing, as well as system design for wireless data communication systems.
