Following on from the success of the first edition, this edition will be revised in light of new developments in near-capacity turbo-transceivers. It will include 5 new chapters on: Multilevel Coding Theory; MLC Design Using EXIT Analysis; Space Time Sphere Packing Aided MLC/ BICM Design; MLC/ BICM Schemes for Wireless Internet and Near-Capacity Irregular BICM-ID Design. The book is divided into the following 4 parts: Part 1 - explains the necessary background for novices. It aims to be both an easy reading text book and a deep research monograph. Part 2 - provides detailed coverage of turbo conventional and turbo block coding considering the known decoding algorithms and their performance over Gaussian as well as narrowband and wideband fading channels. Part 3 – comprehensively discusses both space-time block and space-time trellis coding. Part 4 - provides an overview of turbo equalisations, also referred to as turbo demodulation.
