Inhaltsangabe

THIS BOOK PROVIDES THE FIRST COMPREHENSIVE AND EASY-TO-READ DISCUSSION OF JOINT SOURCE-CHANNEL ENCODING AND DECODING FOR SOURCE SIGNALS WITH CONTINUOUS AMPLITUDES. IT IS A STATE-OF-THE-ART PRESENTATION OF THIS EXCITING, THRIVING FIELD OF RESEARCH, MAKING PIONEERING CONTRIBUTIONS TO THE NEW CONCEPT OF SOURCE-ADAPTIVE MODULATION.THE BOOK STARTS WITH THE BASIC THEORY AND THE MOTIVATION FOR A JOINT REALIZATION OF SOURCE AND CHANNEL CODING. SPECIALIZED CHAPTERS DEAL WITH PRACTICALLY RELEVANT SCENARIOS SUCH AS ITERATIVE SOURCE-CHANNEL DECODING AND ITS OPTIMIZATION FOR A GIVEN ENCODER, AND ALSO IMPROVED ENCODER DESIGNS BY CHANNEL-ADAPTIVE QUANTIZATION OR SOURCE-ADAPTIVE MODULATION.ALTHOUGH INFORMATION THEORY IS NOT THE MAIN TOPIC OF THE BOOK - IN FACT, THE CONCEPT OF JOINT SOURCE-CHANNEL CODING IS CONTRADICTORY TO THE CLASSICAL SYSTEM DESIGN MOTIVATED BY A QUESTIONABLE PRACTICAL INTERPRETATION OF THE SEPARATION THEOREM - THIS THEORY STILL PROVIDES THE ULTIMATE PERFORMANCE LIMITS FOR ANY PRACTICAL SYSTEM, WHETHER IT USES JOINT SOURCE-CHANNEL CODING OR NOT. THEREFORE, THE THEORETICAL LIMITS ARE PRESENTED IN A SELF-CONTAINED APPENDIX, WHICH IS A USEFUL REFERENCE ALSO FOR THOSE NOT DIRECTLY INTERESTED IN THE MAIN TOPIC OF THIS BOOK.SAMPLE CHAPTER(S)CHAPTER 1: INTRODUCTION (98 KB)

Reseña del editor

This book provides the first comprehensive and easy-to-read discussion of joint source-channel encoding and decoding for source signals with continuous amplitudes. It is a state-of-the-art presentation of this exciting, thriving field of research, making pioneering contributions to the new concept of source-adaptive modulation.The book starts with the basic theory and the motivation for a joint realization of source and channel coding. Specialized chapters deal with practically relevant scenarios such as iterative source-channel decoding and its optimization for a given encoder, and also improved encoder designs by channel-adaptive quantization or source-adaptive modulation.Although Information Theory is not the main topic of the book - in fact, the concept of joint source-channel coding is contradictory to the classical system design motivated by a questionable practical interpretation of the separation theorem - this theory still provides the ultimate performance limits for any practical system, whether it uses joint source-channel coding or not. Therefore, the theoretical limits are presented in a self-contained appendix, which is a useful reference also for those not directly interested in the main topic of this book.
