Cognitive Radio Communication and Networking: Principles and Practice

Preface

The idea of writing this book began at least five years ago when the first author taught a one first-year graduate course, on communications/wireless communications. After this course, some students pursued advanced topics such as convex optimization prior to their PhD research. MS students wanted to know more about the field before they began to design wireless systems. The first author taught such advanced courses regularly, and part of these materials provided the starting point for this book. After this book project began, additional authors were added so that we could meet with our deadlines and before the topics become outdated. Another title of this book could be Advanced Wireless Communications.

The most difficult part was to decide what to exclude. The wireless industry is still expanding rapidly after two decades of growth. The first author studied the second generation (2G) system—CDMA and GSM—during his university days. Now, 3G (WCDMA) and 4G (LTE) systems are available. Each system has its central concept and demands unique analytical skills. Generally professors find that their most significant responsibilities are to teach students the most difficult mathematical tools required to analyze and design fundamental system concepts. For example, in a GSM (TDMA) system, the equalizers are central to the system. For a CDMA system, a RAKE receiver is central (as is power control). For an LTE system, a multiple-input, multiple-output (MIMO) system combined with an ...
