Girth-twelveQC-LDPC.rar The program constructs girth-twelve column-weight QC-LPDC codes. The rate can be changed by changing k(row-weight), size is changed by varying m(sub-matrix size).
Girth-eightQC-LDPC.rar The algorith divides rows in to four equal groups. The rows are then used to from a distance graph which is then transformed into a matrix. girth of eight is maintained by avoiding six-cycles in the graph construction
girth4_count.rar The program can count the number of the girth 4 of LDPC codes.
LDPC_BSN.zip LDPC码的硬判决译码算法，即BF算法。其为C语言编写。
LDPC_Behavioral_VHDL.rar 用VHDL语言编写的LDPC码硬件实现语言，相对于verilog的，比较简单
checkNodee_Behavioral_VHDL.rar LDPC码校验节点（checknode）进行奇偶校验方程时的vhdl编程，硬件语言实现
bitNode_Behaviora_VHDL.rar LDPC码的消息节点（Bitnode）消息更新过程的VHDL语言实现
PEG_LDPC.rar 引入PEG（Progressive-edge-growth）算法来构造适合线性时间编码的LDPC校验矩阵，译码时采用简化最小和Min-Sum译码算法实现简化译码．仿真结果表明，该方法能够构造适合LDPC码的线性时间编码的下三角校验矩阵日，并且用此方法构造的LDPC码性能非常接近原来PEG算法构造的LDPC码．同时通过采用最小和Min-Sum算法降低译码复杂度．
ra_ldpc_simple_yqp080717.rar 很好的源代码LDPC，主要实现LPDC概率域上的译码问题
generate_G.rar 数字电视标准矩阵及其生成矩阵源代码（LDPC)
