In order to make up for the performance defects of UMP BP-Based decoding algorithm relative to LLR BP decoding algorithm, a modified UMP BP-Based decoding algorithm is proposed. Parameters of the proposed algorithm are confirmed according to minimum mean square error rule and it has the generality for decoding of all LDPC codes. The simulation results show that the LDPC decoding performance of modified UMP BP-Based decoding algorithm is more effective than that of UMP BP-Based decoding algorithm, Normalized BP-Based decoding algorithm and Offset BP-Based decoding algorithm under the same condition of bit error rate.
