Today's wireless services have come a long way since the roll-out of conventional voice-centric cellular systems. The demand for wireless access in voice and high rate data multi-media applications has been increasing. New generation wireless communication systems are aimed at accommodating this demand through better resource management and improved transmission technologies. This book is both an introductory technology survey/tutorial for beginners and an advanced mathematical overview intended for technical professionals in the communications industry, and technical managers and researchers in both academia and industry. The author investigates cognitive radio and cognitive networks from a broad aspect of wireless communication system enhancement with special emphasis on better spectrum utilization. Coverage includes applications of cognitive radio, SDR and cognitive radio architectures, spectrum efficiency and soft spectrum usage, adaptive wireless system design, measurements and awareness of various parameters including interference temperature and geo-location information.
