中文摘要	A check node degree-based modified min-sum algorithm which classifies the codes was developed to reduce the complexity and improve the performance of decoding algorithm for low-density parity-check (LDPC) codes. The algorithm corrects both the minimum and sub-minimum absolute values of incoming messages in the check nodes. Two correction factors are obtained by calculating the offset between the belief propagation (BP) algorithm and the min-sum algorithm based on the check node degree. Simulations show that the algorithm achieves better performance than the BP algorithm at high signal noise ratio. The algorithm is also less complex than the BP algorithm and provides a good tradeoff between performance and complexity for any check node degree distribution in the LDPC codes.
