Abstract In this article, the main point is to describe the fast decoding algorithm of [256,252] RS extended code. In order to correct the error in the received data quickly, the algorithm gets the error type and error pattern through simple parameter-comparison, then adds the error pattern to the receive data. Compared to the algorithms in existence, this algorithm has the advantages of using less hardware resources and decoding time. When this algorithm implements in hardware, its throughput is more than 400Mbit/s.
