摘要：

In this paper, a novel two-bit bit-flipping (BE) decoding algorithm is proposed for low-density parity-check (LDPC) codes. The proposed algorithm flips two hits per iteration hosed on the syndrome-weight metric. Since the algorithm requires only logical operations during the iterations. The proposed tow-hit BE algorithm has low complexity. Simulation results show that the proposed algorithm has faster convergence speed and about 0.2 dB gain compared to standard BE decoding algorithm.
