译码算法具有重要意义。本文对5GNR标准下的LDPC译码算法进行研究,主要工作如下:首先,提出了一种基于动态因子和震荡均值的类拟合MS(DA-CFMMS)算法。针对基于类拟合修正的MS译码(CFMMS)算法在译码过程中,校验节点信息幅值过高和变量节点信息更新中存在震荡现象,引入次小值和动态因子对校...
Simulation results indicate that the performance of NR LDPC code is better than that of LTE (Long Term Evolution) turbo codes and 802.16e LDPC codes, so the proposed algorithm is effective. Keywords: low density parity code; 5G; base graph; TS 38.212 standard 0 引 言 移动通信已经...
