In this study, a new weighted bit‐flipping (WBF) algorithm called mixed modified WBF (MM‐WBF) decoding is proposed for low‐density parity‐check codes. The new algorithm is built by mixing two WBF algorithms, one acting as the main decoding algorithm and the other acting as the auxiliary. Simulation results show that the new algorithm achieves a notable performance gain over reliability ratio‐based WBF, improved M‐WBF and low‐complexity WBF algorithms with almost the same computational complexity. Compared with some belief‐propagation‐based algorithms, MM‐WBF also provides an appealing performance against complexity trade‐off.
