Cognitive/adaptive radios gradually find their way into the new generations of wireless systems. Such radios search for the unused parts of the spectrum that are owned by the primary users, whenever they are available, to establish communication on an opportunistic basis. Implementation of any cognitive radio network requires an effective control channel that can operate under various primary users activity conditions. This talk presents the design and implementation of a filter bank multicarrier spread spectrum (FBMC-SS) for the control channel in cognitive radio networks. An implementation of the proposed FBMC-SS system on a hardware platform is presented. Practical hurdles encountered in this implementation and lessons learnt are also discussed.
Dr. Behrouz Farhang is a professor of Electrical and Computer Engineering at the University of Utah. He is an expert in the general area of signal processing. His current scientific interests are adaptive filters, multicarrier communications, detection techniques for space-time coded systems, and cognitive radios. In the past, he has worked and has made significant contribution to areas of adaptive filters theory, acoustic echo cancellation, magnetic/optical recoding, and digital subscriber line and wireless technologies. He is the author of the books “Adaptive Filters: theory and applications”, John Wiley & Sons, 1998 and 2013 (2nd edition), and “Signal Processing Techniques for Software Radios”, self published at Lulu publishing house, 2009 and 2010 (2nd edition).
