摘要：

In this paper, a two-staged decoding strategy which can be used for the Weighted Bit Flipping (WBF) based decoding algorithm for LDPC codes is presented. At the two stages, a parallel WBF and bit-flipping (BF) algorithms are adopted separately. Correspondingly, by the study of the iterative decoding process of the PWBF algorithm, a simple function is introduced to dynamically implement the switch of two decoding stages. The proposed algorithm can noticeably lower the error floor of PWBF algorithm with a modest increase in computation complexity and hardware cost. The validation of the proposed algorithm is verified by simulation.
