Recent developments such as the invention of powerful turbo-decoding and
irregular designs, together with the increase in the number of potential
applications to multimedia signal compression, have increased the
importance of variable length coding (VLC). Providing insights into the
very latest research, the authors examine the design of diverse
near-capacity VLC codes in the context of wireless telecommunications.
The book commences with an introduction to Information Theory, followed
by a discussion of Regular as well as Irregular Variable Length Coding
and their applications in joint source and channel coding. Near-capacity
designs are created using Extrinsic Information Transfer (EXIT) chart
analysis. The latest techniques are discussed, outlining radical
concepts such as Genetic Algorithm (GA) aided construction of diverse
VLC codes. The book concludes with two chapters on VLC-based space-time
transceivers as well as on frequency-hopping assisted schemes, followed
by suggestions for future work on the topic.
