Modified Bit-Flipping Decoding of Low-Density Parity-Check codes
A novel bit-flipping (BF) algorithm with low complexity for high-throughput decoding of low-density parity-check (LDPC) codes is presented.At each iteration,a novel threshold pattern is used to determine the code bits whether to be flipped or not,and the flipping error probability is effectively decreased.Compared with the weighted BF algorithm and its modifications,the modified BF algorithm has significantly lower complexity and decoding time.Through simulations the proposed BF algorithm is shown to achieve excellent performance and fast convergence speed while maintaining significantly low complexity thus facilitating high-throughput decoding.
