Témata: Parallel concatenated coding, iterative decoding, code performance, Error-Control Coding system reliability
Popis: Iterative coding systems are currently being proposed and accepted for many future systems as next generation wireless transmission and storage systems. The text gives an overview of the state of the art in iterative decoded FEC (Forward Error-Correction) error-control systems. Such systems can typically achieve capacity to within a fraction of a dB at unprecedented low complexities. Using a single code requires very long code words, and consequently very complex coding system. One way around the problem of achieving very low error probabilities is turbo coding (TC) application. A general model of concatenated coding system is shown - an algorithm of turbo codes is given in this paper.
