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.
