Abstract :
In this paper, we propose a combined modified weighted bit-flipping (CM-WBF) algorithm for low-density parity-check (LDPC) codes. The new algorithm combines modified weighted bit-flipping (M-WBF) with low complexity weighted bit-flipping (LC-WBF). Simulation results show that the new algorithm offers a better trade-off among performance, complexity, and convergence compared with M-WBF, LC-WBF and RR-WBF algorithms for finite geometry LDPC (FG-LDPC) codes.
