Near–Capacity Variable–Length Coding: Regular and EXIT–Chart–Aided Irregular Designs

This book provides a cutting edge explanation of VLC codings and their future developments.
Near–Capacity Variable–Length Coding examines the topic in the context of digital multimedia broadcast telecommunications. Providing insight into VLC coding’s applications, characteristics and performance, the book addresses the latest research in the area. Using novel experiments, it systematically introduces Irregular Variable Length Coding (IrVLC), its function in joint source and channel coding, employment to facilitate Unequal Error Protection (UEP) and application to near–capacity operation using Extrinsic Information Transfer (EXIT) chart analysis. Having introduced the topic thoroughly, the mid section is devoted to the authors’ latest techniques, outlining and explaining concepts such as Genetic Algorithm (GA), constructing both RVLCs and VLEC codes and EXIT modules. The book concludes with a chapter on future work on the topic.

–       Provides an exhaustive treatment of variable length coding systems and their application to error–prone transmission systems
–       One of the first titles to address the subject in such depth, including latest research results
–       Topics include: the effect of different free distances of the source codes; vector quantised RVLC–TCM scheme and EXIT systems
