摘要：
An improved weighted bit-flipping decoding algorithm for LDPC codes is presented. The proposed algorithm introduces an updating rule for variable nodes to efficiently improve the reliability of the flipped bits and reduces the error codes caused by the oscillation of the loops. Simulation results show that the proposed algorithm achieves better BER performance than the Sum of Magnitude based Weighted Bit-Flipping (SMWBF) decoding algorithm over the additive white Gaussian noise channel with only a small increase in computational complexity. © 2016, Science Press.
