李伟华 %A 焦秉立 %J 电子与信息学报 %D 2008 %I %X A decoding method for LDPC codes concatenated by multiple Cyclic Redundancy Checks (CRCs) has improved the convergence of the decoding effectively. However, the error floor of the decoding appears due to the high overall Undetected Error Probability (UEP) of CRCs. Therefore, This work improves the Codeword Error Rate (CER) performance further based on the fact that the overall UEP of CRCs in decoding can be reduced when the application times of CRCs checking are decreased. The simulation results show the performance improvements in terms of CER, while decoding complexity is slightly increased. %K 低密度奇偶校验码 %K 循环冗余校验 %K 置信度传播算法 %K 分段 %K LDPC %K 译码复杂度 %K 改进算法 %K Redundancy %K Cyclic %K Aided %K Algorithm %K Decoding %K Method %K 仿真 %K 误码性能 %K 误码平台 %K 漏检概率 %K 检测 %K 收敛特性 %K 改善 %K 译码算法 %K 循环冗余校验 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=1319827C0C74AAE8D654BEA21B7F54D3&jid=EFC0377B03BD8D0EF4BBB548AC5F739A&aid=8E5AB8CCEDEEF5A97DAB8BA91F3C5FF9&yid=67289AFF6305E306&vid=340AC2BF8E7AB4FD&iid=94C357A881DFC066&sid=9905045FEE51B18F&eid=75AB4EF959CC4ED9&journal_id=1009-5896&journal_name=电子与信息学报&referenced_num=0&reference_num=8
