Turbo Coding, Turbo Equalisation and Space-Time Coding

Beschreibung

Turbo coding has opened an exciting new chapter in the design ofiterative detection assisted communication systems. Similardramatic advances have been achieved with the advent of space timecoding, when communicating over dispersive fading wirelesschannels. By assuming no prior knowledge in the field of channelcoding, the authors provide a self-contained reference on thesestimulating hot topics, concluding at an advanced level. This essential volume is divided into five key parts: 1. Convolutional and Block Coding Introduces the family of convolutional codes, hard andsoft-decision Viterbi algorithms and the most prominent classes ofblock codes, namely Reed-Solomon (RS) andBose-Chaudhuri-Hocquenghem (BCH) codes, as well as their algebraicand trellis-decoding. 2. Turbo Convolutional and Turbo Block Coding Introduces turbo convolutional codes and details the MaximumA-Posteriori (MAP), Log-MAP and Max-Log-MAP as well as the SoftOutput Viterbi Algorithm (SOVA). Investigates the effects of thevarious turbo codec parameters. Studies the super-trellis structureof turbo codes and characterises turbo BCH codes. PortraysRedundant Residue Number System (RRNS) based codes and their turbodecoding. 3. Coded Modulation: TCM, TTCM, BICM, BICM-ID Studies Trellis Coded Modulation (TCM), Turbo Trellis CodedModulation (TTCM), Bit-Interleaved Coded Modulation (BICM),Iterative BICM (BICM-ID) and compares them under various channelconditions. 4. Space-Time Block and Space-Time Trellis Coding Introduces space-time codes and studies their performance usingnumerous channel codecs providing guidelines for system designers.Studies Multiple-Input Multiple-Output (MIMO) based schemes and theconcept of near-instantaneously Adaptive Quadrature AmplitudeModulation (AQAM) combined with near-instantaneously adaptive turbochannel coding. 5. Turbo Equalisation Covers the principle in detail, provides theoretical performancebounds for turbo equalisers and includes a study of various turboequaliser arrangements. Also addresses the problem of reducedimplementation complexity and covers turbo equalised space-timetrellis codes. If you are looking for a comprehensive treatment covering bothclassic channel coding techniques and recent advances in thisfield, then this is the book for you. Researchers, practisingengineers and advanced students will all find it both informativeand stimulating.
