Joint Source-channel Coding Of Discrete-time Signals With Continuous Amplitudes: 1 (Communications and Signal Processing) - Tapa dura

Sinopsis

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)
