BCH DECODING METHOD AND DECODER THEREOF

摘要

The present disclosure illustrates a BCH decoding method and a decoder thereof. In this BCH decoding method, the BCH decoder receives an encode data at first, then calculates a syndrome of the encode data. After calculating the syndrome of the encode data, the BCH decoder calculates at least one error location of the encode data in response to the syndrome. Next, the BCH decoder detects at least one determining bit which a first bit string of the encode data comprises. Finally, an error correction is then performed based upon the error location, such that the BCH decoder outputs decode data.
