Error correcting coding is often analyzed in terms of itsapplication to the separate levels within the data network inisolation from each other. In this fresh approach, theauthors consider the data network as a superchannel (amulti-layered entity) which allows error correcting coding to beevaluated as it is applied to a number of network layers as awhole. By exposing the problems of applying error correctingcoding in data networks, and by discussing coding theory and itsapplications, this original technique shows how to correct errorsin the network through joint coding at different networklayers.* Discusses the problem of reconciling coding applied todifferent layers using a superchannel approach
* Includes thorough coverage of all the key codes: linear blockcodes, Hamming, BCH and Reed-Solomon codes, LDPC codes decoding, aswell as convolutional, turbo and iterative coding
* Considers new areas of application of error correcting codessuch as transport coding, code-based cryptosystems and coding forimage compression
* Demonstrates how to use error correcting coding to control suchimportant data characteristics as mean message delay
* Provides theoretical explanations backed up by numerousreal-world examples and practical recommendations
* Features a companion website containing additional researchresults including new constructions of LDPC codes, jointerror-control coding and synchronization, Reed-Muller codes andtheir list decoding

By progressing from theory through to practical problem solving,this resource contains invaluable advice for researchers,postgraduate students, engineers and computer scientists interestedin data communications and applications of coding theory.
