| 摘 要： | 分析了LDPC码置信传播译码算法，研究了置信传播译码算法过程中传递消息的收敛特性，提出了一种旨在降低算法迭代次数的修正的BP算法．仿真结果表明，该算法的迭代次数约为标准BP算法的1／2，但性能的恶化并不大

| Abstract: | This paper analyzed the Belief-Propagation decoding algorithm for Low-Density Parity Check Codes and researched the convergence characteristic of this algorithm,and then proposed a modified Belief-Propagation decoding algorithm aiming at decreasing the number of iteration.Simulation result shows that the number of iteration of the proposed algorithm is only one-third of the standard one at expense of little loss in performance. |
