Abstract
A method and system for LDPC decoding method. In the method and system, an LDPC codeword is decoded using a quasi-cyclic matrix. A first message for variable nodes in a circulant column of the quasi-cyclic matrix and a second message for check nodes belonging to the circulant column are computed. Parity and syndrome are computed using the computed first and second messages. A bit error rate is calculated for both a first mode with no error in a parity portion of a codeword and a second mode with errors in the parity portion of the codeword.
