Advanced Error-Control Coding Methods Enhance Reliability of Transmission and Storage Data Systems

Abstract

Iterative coding systems are currently being proposed and acceptedfor many future systems as next generation wireless transmission andstorage systems. The text gives an overview of the state of the art initerative decoded FEC (Forward Error-Correction) error-control systems.Such systems can typically achieve capacity to within a fraction of adB at unprecedented low complexities. Using a single code requires verylong code words, and consequently very complex coding system. One wayaround the problem of achieving very low error probabilities is turbocoding (TC) application. A general model of concatenated coding systemis shown - an algorithm of turbo codes is given in this paper.
