Quadrature Amplitude Modulation: From Basics to Adaptive Trellis-Coded, Turbo-Equalised and Space-Time Coded OFDM, CDMA
Motivated by the rapid evolution of the consecutive generations of wireless communication systems, this volume continues to provide an overview of the majority of single and multi carrier QAM techniques. Now fully revised and updated, with more than 300 pages of new material, this new edition presents the wide range of recent developments in the field and places particular emphasis on the family of coded modulation aided OFDM and CDMA schemes. In addition, it also includes a fully revised chapter on adaptive modulation and a new chapter characterizing the design trade offs of adaptive modulation and space time coding. Divided into four parts, Part I commences with a historical perspective and classic schemes for the uninitiated. Part II offers a deep discourse on adaptive QAM arrangements that have found their way also into the 3G system's High Speed Data Packet Access (HSDPA) mode. Part III details the advanced intricacies of adaptive versus space time block and trellis coded OFDM and MC CDMA. Part IV contains previously unpublished new research results. It commences with a theoretical chapter on the capacity of wireless channels. The discussions then continue by contriving sophisticated iterative coded modulation systems, such as TCM, TTCM, BICM, BICM ID designed for turbo detected QAM based space time coded OFDM and CDMA systems operating over wireless channels. In summary, this volume amalgamates a comprehensive textbook with a deep research monograph on the topic of QAM, ensuring it has a wide ranging appeal for both senior undergraduate and postgraduate students as well as practicing engineers and researchers.
Why Read This Book
You should read this book if you need a single, in-depth resource that links the fundamentals of QAM to practical, modern wireless techniques such as OFDM, CDMA, trellis/turbo-coded modulation and space–time coding; it balances theory, performance analysis and implementation-oriented discussions. You will get worked examples, performance trade-offs and design guidance that are directly applicable when designing or simulating contemporary digital communication systems.

How It Compares
Covers similar ground to Proakis' Digital Communications and Tse & Viswanath's Fundamentals of Wireless Communication but is more applied and focused on QAM, coded modulation, OFDM/CDMA and practical iterative receiver techniques; Hanzo emphasizes engineering trade-offs and implementation detail more than pure mathematical proofs.
