LDPC码编译码算法的研究与实现_陈石平
本文首先回顾了LDPC码的发展历程和现状,介绍了LDPC码检验矩阵的构造、编
译码原理。在对编译码作了深入探讨和分析后,接着进行了RU算法编码和长码编码
的FPGA实现;根据二叉树的性质,提出了一种长码编码的ASIC优化设计的方法,节省
了大量硬件资源;论文详细阐述了CORDIC算法原理以及LDPC码译码中所采用的指
数函数和反双曲正切函数的FPGA实现:CORDIC内核及前后处理单元设计、仿真、综
合及数据分析,这对LDPC码的译码具有很重要的意义,为用数字VLSI来实现LDPC的
译码奠定了基础。同时在基于校验矩阵的环路检测定理基础上,将校验矩阵转化为转
移概率矩阵,详细分析并提出了一种基于转移概率矩阵的围长检测方法,并对其进行
了理论证明,具有很好的围长检测效果,以及状态分类判别。(Research and implementation of LDPC coding and decoding technology)
