Description: 基于穷举法实现的LDPC码的校验H矩阵的自动生成程序，并且有一定的去小环的功能。如果最后的结果趋缓结果不理想，可以适当加大变量GENE的初始值，它表明程序穷举的次数，预置为500次。-Method Based on the exhaustive LDPC check matrix H automatic generation procedures, and to a certain small part of the function. If the final results of the slowdown in the outcome is unsatisfactory, it may be appropriate variables LCRA increase on the initial value It shows that the number of procedures exhaustive, preset to 500.

Description: There is an example of how to use the LDPC encode/decode with AWGN
channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m.
There are a few parity check matrices available in the code but
you can use other matrices provided you have enough memory to load
them. I suggest checking out matrices in Alist format available on
David MacKay s web site.You will need to have access to a MEX compiler
to be able to use a few functions written in C.

Description: 利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),-use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),

Description: A novel class of bit-flipping (BF) algorithms for
decoding low-density parity-check (LDPC) codes is presented.
The proposed algorithms, which are called gradient descent bit
flipping (GDBF) algorithms, can be regarded as simplified gradient
descent algorithms. Based on gradient descent formulation,
the proposed algorithms are naturally derived a simple
non-linear objective function-A novel class of bit-flipping (BF) algorithms for
