A Review :Implementation of Reed Solomon Error Correction & Detec-tion For Wireless Network 802.16

Abstract

The reed Solomon (255,239) are error-correcting & detecting code. Reed-Solomon codes are the most frequently used digital error control. It is also called as forword error code. The main part of reed-Solomon encoder is the linear feedback shift register that is implemented using VHDL A pipelined RS decoders is proposed of reducing the hardware complexity use the pipelined GFmultiplier in the syndrome computation block, KES block, Forney block, Chien search block and error correction block for provides low com-plexity the extended inversion less Massey-Berlekamp algorithm is used. The extended inversion less Massey-Berlekamp algorithm overcomes both the error locator polynomial and the error evaluator polynomial at the same time.
