A comprehensive text that covers both receiver and transmitter circuits, reflecting the past decade's developments in solid-state technology. Emphasizes design using practical circuit elements, with basic ideas of electrical noise, resonant impedance-matching circuits, and modulation theory thoroughly explained. Contains the latest techniques in radio frequency power amplifier design, accepted state-of-the-art technology based on bipolar junction transistors, VMOS RF power FETs, high-efficiency techniques, envelope elimination and restoration, envelope feedback, and other newly emerging technologies. Requires a knowledge of complex algebra, Fourier series, and Fourier transforms. Also includes numerous worked-out examples that relate the theory to practical circuit applications, and homework problems keyed to corresponding sections of the text.

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.
