Modified channel-independent weighted bit flipping decoding algorithm for low-density-parity-check codes

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...

Popis
Shrnutí: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.
