What is Modified WBF Decoding for LDPC Codes about?

This document presents a modified weighted bit-flipping (WBF) decoding algorithm for low-density parity-check (LDPC) codes, which incorporates both check and bit messages to enhance performance. The proposed method shows improvements in bit error rates and requires fewer iterations compared to the standard WBF algorithm, particularly for longer codes. However, the optimal weighting factor is dependent on the signal-to-noise ratio (SNR), although maintaining a constant factor at a chosen optimal SNR does not
