Abstract
Methods and systems are provided for decoding LDPC codewords or blocks of codewords using a second set of parameters if decoding the codewords or blocks of codewords fails using a first set of parameters. An LDPC codeword may be decoded using a first decoding technique to produce a first decoding output using a first parameter. The first parameter may be altered to generate a second parameter to be used in a second decoding technique. The LDPC codeword may be decoded using the second decoding technique to produce a second decoding output. A syndrome weight of the first decoding output may be compared to a syndrome weight of the second decoding output and one of the first decoding output or the second decoding output may be selected based on which of the first decoding output or the second decoding output has a lower error.
