A cognitive radio is a transceiver which is aware of its environment, its own technical capabilities and limitations, and those of the radios with which it may communicate; is capable of acting on that awareness and past experience to configure itself in a way that optimizes its performance; and is capable of learning from experience. In a real sense, a cognitive radio is an intelligent communications system that designs and redesigns itself in real time.

Cognitive Radio Engineering is both a text and a reference book about cognitive radio architecture and implementation, intended for readers who want to design and build working cognitive radios. It takes the reader from conceptual block diagrams through the design and evaluation of illustrative prototypes. An important goal is to bridge the divide between radio engineers, who often have little experience with the computational resource and timing issues inherent in cognitive radios, and computer engineers who often are unaware of RF issues like dynamic range, intermodulation products, and acquisition time.

Following a brief overview of cognitive radio history and a high-level look at cognitive radio operation, the book presents a detailed study of cognitive engine design and analysis. After treating RF subsystems the book considers computational platforms and computation issues in cognitive radios, followed by system integration, evaluation methods for cognitive radio, and cognitive radio design for networking. The book concludes with coverage of cognitive radio applications in communications.

Charles W. Bostian is the Alumni Distinguished Professor Emeritus of Electrical and Computer Engineering at Virginia Tech, USA. His students and he have made many contributions to cognitive radio, including developing the basic terminology and building some of the first working prototypes. Bostian has co-authored three other radio communications books, several book chapters, and a number of journal articles and conference presentations.

Nicholas J. Kaminski conducts research focused on extending the bounds of wireless technology by deploying targeted intelligence to act in harmony with flexible radio systems. He advances distributed radio intelligence through experimentation-based research and is co-principal investigator on several European projects that create and develop experimentation platforms and services for wireless research. He also furthers wireless communications by incorporating techniques for understanding communications from complex systems science.

Almohanad S. Fayez is a Software Engineer at Intel in Sort Test Technology Development (STTD) where he is involved in the design and development of Intel's next generation of silicon test modules. His interests include high performance computing, embedded systems, software defined radio, wireless networks while focusing on implementation and practical system considerations.
