摘要：Low Density Parity Check(LDPC)codes is one of the high topics of the channel coding theory and has been paid more and more attention．In this paper，a modified decoding algorithm based on the belief propagation(BP) algorithm is proposed．It normalizes the variable message to compensate the simplified check message for reducing complexity. The simulation results show that the proposed algorithm can improve the BER property and reduce the computation complexity．
