Error correcting coding is often analyzed in terms of its
application to the separate levels within the data network in
isolation from each other. In this fresh approach, the
authors consider the data network as a superchannel (a
multi-layered entity) which allows error correcting coding to be
evaluated as it is applied to a number of network layers as a
whole. By exposing the problems of applying error correcting
coding in data networks, and by discussing coding theory and its
applications, this original technique shows how to correct errors
in the network through joint coding at different network
layers.
* Discusses the problem of reconciling coding applied to
different layers using a superchannel approach
* Includes thorough coverage of all the key codes: linear block
codes, Hamming, BCH and Reed-Solomon codes, LDPC codes decoding, as
well as convolutional, turbo and iterative coding
* Considers new areas of application of error correcting codes
such as transport coding, code-based cryptosystems and coding for
image compression
* Demonstrates how to use error correcting coding to control such
important data characteristics as mean message delay
* Provides theoretical explanations backed up by numerous
real-world examples and practical recommendations
* Features a companion website containing additional research
results including new constructions of LDPC codes, joint
error-control coding and synchronization, Reed-Muller codes and
their list decoding
By progressing from theory through to practical problem solving,
this resource contains invaluable advice for researchers,
postgraduate students, engineers and computer scientists interested
in data communications and applications of coding theory.
