Cognitive radio is a hot research area for future wireless communications in the recent years. In order to increase the spectrum utilization, cognitive radio makes it possible for unlicensed users to access the spectrum unoccupied by licensed users. Cognitive radio let the equipments more intelligent to communicate with each other in a spectrum-aware manner and provide a new approach for the co-existence of multiple wireless systems.
The goal of this book is to provide highlights of the current research topics in the field of cognitive radio systems. The book consists of 17 chapters, addressing various problems in cognitive radio systems.
Chapter 1 - Chapter 3 introduce the concepts and the state-of-the-art strategies for cognitive radio systems.
Chapter 4 - Chapter 6 focus on the spectrum sensing techniques for cognitive radio systems, including cooperative spectrum sensing, cyclostationary-based signal detection and sensing-based traffic patte prediction.
Chapter 7 - Chapter 10 provide some recent research achievements on the transmission technologies. Two of them describe the interference related transmission, while the other two chapters study the multi-antenna transmission for cognitive radio systems.
Chapter 11 - Chapter 15 present the efficient solutions for various resource allocation problems, including MAC protocol, subband selection, power allocation, resource management and the transmission for multimedia services.
Chapter 16 - Chapter 17 discuss some practical issues in cognitive radio systems. The platform for inter-radio system switching and the power amplification are investigated in the two chapters respectively.
