[VHDL-FPGA-Verilog] Realization_of_FPGA_for_LDPC_encoding

Description: 低密度奇偶校验码(简称LDPC码)是目前距离香农限最近的一种线性纠错码，它的直接编码运算量较大，通常具有码长的二次方复杂度．为此，利用有效的校验矩阵，来降低编码的复杂度，同时研究利用大规模集成电路实现LDPC码的编码．在ISE 8．2软件平台上采用基于FPGA的Verilog HDL语言实现了有效的编码过程，为LDPC码的硬件实现和实际应用提供了依据-Abstract：Low．density parity·check code(LDPC code)is a kind of linear eror·correcting code nearest to Shannon Limit．For LDPC cod e，the computational overhead for direct encoding operations is large，as the complexity of encod ing is the square of the length of codeword．Hence，this paper reduces the complexity of coding by using effective parity—check matrix，and realizes the encoding device for LDPC code by use of large·scale integrated circuits．The effective encoding process based on FPGA with Verilog HDL language is implemented on ISE 8．2 software platform ，providing a feasible basis for hardware implementation an d practical application of LDPC code．

[matlab] LDPC码编译码算法的研究与实现_李会雅

Description: 本文首先介绍了几种LDPC码的编译码算法，同时推导了译码错误概率和密度进化过程，讨论了信道参数的门限效应。接着对LDPC码二分图中长度为4的环进行了深入研究，提出了一种LDPC码校验矩阵的消4一环生成算法，采用Matlab和VC++融合编程方式，完成了此算法的程序设计。此算法不仅可生成二进制LDPC码的校验矩阵，并且对算法修正后，也可生成多进制LDPC码的校验矩阵。采用此算法后可避免LDPC码译码过程中的重复迭代，显著提高了短帧LDPC码的误比特率性能。同时对不同参数对 LDPC码性能的影响进行了仿真，得到了一些结论。最后，利用VHDL语言在复杂可编程逻辑器件(CPLD)上完成了LDPC码编码器的硬件实现。另外，给出了LDPC码译码器硬件实现的整体结构图，结合对数似然比域内的置信传播迭代译码(LLR-BP)算法，对译码器的各个模块进行了详细阐述。(Research and implementation of LDPC coding and decoding technology)
