摘要

RS(32,28)码普遍用于光盘播放机。本文提出了一种采用元胞自动机(CA)规则结构的RS(32,28)编码器和解码器的模块化结构。该工作还可以识别现有相关工作中的错误,并对其进行纠正,以定位双重错误。提出的基于CA的双纠错编解码器可以很容易地扩展到3,4,5字节的纠错码。基于ca的VLSI设计因其简单、规则和高吞吐量而具有吸引力。

Design and Implementation of RS (32, 28) Encoder and Decoder Using Cellular Automata
RS (32, 28) code is popularly used for compact disk player. In this work, a modular architecture of RS (32, 28) encoder and decoder employing the regular structure of Cellular Automata (CA) has been proposed. The work also identifies a mistake in an existing related work and recti- fies it for locating double errors. The proposed CA based double error correcting codec can be easily extended to 3, 4, 5 byte error correcting codes. CA-based VLSI design is attractive because of its simplicity, regularity and higher throughput.
