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: LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。
-LDPC Coding with PSK modulation in Rayleigh fading channel
Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements.
In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.
Please feel free to contact me and let me know your comments.

Description: Specify the condition to stop the decoding iterations as one of Maximum iteration count | Parity check satisfied . The default is Maximum iteration count . When you set this property to Maximum iteration count , the object will iterate for the number of iterations you specify in the Maximum Iteration Count property. When you set this property to Parity check satisfied , the object will determine if the parity checks are satisfied after each iteration and stops if all parity checks are satisfied.-Specify the condition to stop the decoding iterations as one of Maximum iteration count | Parity check satisfied .
