摘要 针对G.hn标准中QC-LDPC译码算法设计,提出了一种适合芯片设计的算法。该算法从LDPC译码过程的调度机制和节点更新算法2方面研究了其不同组合下的译码算法的性能和复杂度,实现了适合G.hn标准QC-LDPC译码算法———LBP-NMS算法。仿真结果表明,该算法最大迭代次数为10,误码性能良好,计算量较低,能满足G.hn标准下芯片设计的需要。 Aiming at decoding algorithm for chip design based on the G.hn standard,an algorithm which is suitable for chip design is provided.LDPC decoding algorithm is studied in different combinations:the LDPC decoding process scheduling mechanism and node update process.Finally,the LBP-NMS algorithm was provided.The simulation result shows that LBP-NMS algorithm has good performance and lower complexity if the number of iterations is 10and that is suitable for the chip design in G.hn standard.
