Abstract
In this study, a modified channel-independent weighted bit flipping (CIWBF) decoding algorithm is proposed for low-density-parity-check codes. This modification, based on the `additive offset term adjustment´ in the reliability of the check sum, can also be applied to the reliability ratio weighted bit flipping algorithm. Simulation results show that the performance of the author´s improved modified CIWBF algorithm is better than that of CIWBF algorithm about 0.45 dB at bit-error rate of 10-5 over an additive white Gaussian noise channel without much complexity increase.
