    摘要: A method for a decoding device to decode a codeword matrix of a product code includes: generating a first extended parity check matrix for a vertical code; decoding a horizontal codeword of a plurality of rows in the codeword matrix to thus perform a first decoding process; generating a second extended parity check matrix by removing a column corresponding to a row of the first decoding-succeeded horizontal codeword from the first extended parity check matrix; and decoding the first decoding-failed horizontal codeword by using the second extended parity check matrix to thus perform a second decoding process. Therefore, the simple and reliable product code decoding method is provided.
