Abstract: A decoding algorithm for quadratic residue codes applicable to the decoding of all quadratic residue codes is provided. The decoding algorithm employs digital signals to obtain a plurality of known syndromes. These known syndromes are used to calculate a plurality of unknown syndromes. The inverse-free Berlekamp-Massey algorithm is then used to calculate the error polynomial, after which the Chien search algorithm is used to determine the error locations. Adjustments can then be made to the digital signal bits corresponding to the error locations to obtain the correct code.

Abstract: A decoding method of a cyclic code decoder includes the machine-implemented steps of: establishing a lookup table; receiving a codeword; computing a syndrome and a Hamming weight; if the Hamming weight is not equal to zero and not greater than an error correcting capability value, performing a first error correcting operation; if the Hamming weight is greater than the error correcting capability value, and if the syndrome has a matching syndrome pattern in the lookup table, performing a second error correcting operation; if a second Hamming weight corresponding to a syndrome difference is smaller than a check value, performing a third error correcting operation, otherwise performing a fourth error correcting operation; and if a counter value is greater than zero, performing a fifth error correcting operation before decoding a corrected codeword.

Abstract: An error detection module includes a known-syndrome computing unit, an unknown-syndrome computing unit, and an error detection unit. The known-syndrome computing unit is operable to convert a received signal into a target signal, to obtain known syndromes based upon the target signal, and to generate an errata-locator polynomial based upon an erasure-locator polynomial and the known syndromes. The unknown-syndrome computing unit is operable to compute unknown syndromes based upon the errata-locator polynomial and the known syndromes. The error detection unit is operable to obtain a syndrome set that includes the known syndromes and the unknown syndromes, to obtain an error detection signal according to the syndrome set, and to provide an error correction module coupled thereto with the syndrome set and the error detection signal for enabling the error correction module to correct an error of the received signal.
