Abstract :
The book reviewed is, "Principles of Cognitive Radio" (Biglieri, E.; 2012). This book has five chapters, each intended by the authors to be a self contained unit for the reader. The first chapter introduces the concepts and technology of CR, presents standardization policies in place and planned for the future, and examines design of scalable CR networks. Chapter 2 details the information theoretic side of CR networks, The chapter also presents guidelines for the spectral efficiency that can be achieved by the three CR paradigms proposed in the literature: underlay, overlay, and interweave, and the corresponding capacity regions for each paradigm. Chapter 3 presents propagation issues in CR networks. Chapter 4 deals with spectrum sensing to be used especially in the interweaving and underlay paradigms. Chapter 5 deals with spectrum exploration and exploitation including advanced spectrum sensing technologies, such as distributed detection and sequential and quick detection. The book does not cover networking aspects of CR, protocols, and standardization efforts, as acknowledged by the authors. However, this book is a good starting point for a graduate class in cognitive radio, a good introduction for new researchers, and a good reference book for practitioners.
