| Abstract: | The Reed-Solomon code is a non-binary BCH code, and the RS code can correct not only random errors but also burst errors. It is widely used in the communications and data storage systems. This paper introduces the method of decoding to improve the reliability in high-speed data storage systems. RS timing simulation shows that the decoder can achieve maximum correction. |
