As the demand for data reliability increases, coding for error control becomes increasingly important in data transmission systems and has become an integral part of almost all data communication system designs. In recent years, various trellis-based soft-decoding algorithms for linear block codes have been devised. New ideas developed in the study of trellis structure of block codes can be used for improving decoding and analyzing the trellis complexity of convolutional codes. These recent developments provide practicing communication engineers with more choices when designing error control systems. Trellises and Trellis-based Decoding Algorithms for Linear Block Codes combines trellises and trellis-based decoding algorithms for linear codes together in a simple and unified form. The approach is to explain the material in an easily understood manner with minimal mathematical rigor. Trellises and Trellis-based Decoding Algorithms for Linear Block Codes is intended for practicing communication engineers who want to have a fast grasp and understanding of the subject. Only material considered essential and useful for practical applications is included. This book can also be used as a text for advanced courses on the subject.

This book presents the most important features, results and techniques of trellis coding which have appeared in the literature over the past 15 years. It is a summary as well as a basis for anyone involved in trellis coding applications or research. Engineers, communications specialists, telecommunications experts, scientists, mathematicians and students will find this book an invaluable resource.

This supplement contains worked out solutions to the chapter end problem sets found in Digital Communication, Second Edition, ISBN 0-7923-9391-0.

This book is an excellent reference for those working in the broad fields of communication theory, information theory, and modem design. It is essential for researchers in modulation and coding for voiceband telephone line modems; signal constellation design; nonlinear precoding for modems; and trellis coding. The author presents the theory behind the new modulation and coding techniques included in ITU-T Recommendation V.34. Topics discussed include signal constellation shaping by shell mapping, nonlinear precoding, four-dimensional trellis codes, and fast equalizer training by using periodic sequences and FFT methods. In addition, several approaches that were considered but not accepted are presented including trellis shaping, trellis precoding, and modulus conversion.

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.
