Synopsis

This book provides an excellent mix of theory and practice. Starting with information theory and classical coding theory, the text covers the message passing concept that forms the basis of modern coding techniques, including turbo codes and Low Density Parity Check (LDPC) codes, and then discusses a large number of turbo code combinations - including industry standards, such as DVB-RCS, 3GPP, and CDMA2000. Numerous implementation issues and examples of commercially available turbo codes and products are explored in detail. This comprehensive treatment of the topic will enable the reader to select, evaluate, and implement the turbo code suitable for their application. Programs for the simulation of several turbo coding schemes, including those in DVB-RCS and 3GPP standards, are included in the accompanying CD-ROM. These C programs can be easily used for simulation and performance evaluation and serve as a starting point for a design effort. FPGA, ASIC, and DSP sample implementations are also presented. Source files, instead of executables, are included so that the reader can modify the programs and tailor them to his/her needs.
