摘要

本文提出了一种新的LDPC码解码技术“MP-VSD”。它结合了硬决策消息传递(HDMP)和矢量符号解码(VSD)。VSD通常使用非常短的分组码来限制错误符号的数量,这限制了VSD解码步骤中所需的矩阵反演的大小。在2状态衰落信道模型中,MP-VSD对(60,30)LDPC码在无矩阵反转的情况下,可校正VSD可校正错误模式的60%以上。因此,较长的分组码可以用于非二进制符号。

Message Passing-Vector Symbol Decoding for LDPC Codes with Nonbinary Symbols
This paper proposes a new decoding technique called “MP-VSD” for LDPC codes with large nonbinary symbols. It combines Hard Decision Message Passing (HDMP) with Vector Symbol Decoding (VSD). VSD usually uses very short block codes to limit the number of error symbols, which limits the size of matrix inversion required in the VSD decoding step. MP-VSD can correct more than 60% of the correctable error patterns of VSD for an (60, 30) LDPC code with no matrix inversions in a 2-state fading channel model. Thus, longer block codes may be used for nonbinary symbols.
