Description: LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G)

Description: Low Density Parity Check (LDPC) 信道编码的C程序。二部图连接关系的输入在20000.10000.3.631.txt 文件中。文件中的参数包括check，ariable节点的度数，具体的连接关系。可根据具体需要，需改你所需的txt文件，从而实现任意参数的LDPC程序仿真。经验证，此程序的性能正确，符合理论文献中的结果。-Low Density Parity Check (LDPC) codes simulation C program. This program is developed by Seishi Takamura in Stanford University. This program can realized the simulation of ber performance of regular LDPC codes. The code structure is defined by the*.txt file including the check node degree, variable node degree and the connection indices between the nodes in the bipartite graph. If you want to simulate LDPC codes with other parameters, you can only modify this input .txt file. I have tested this program and the logic is correct and performance is also accurate in the Bit error rate. In addition, the syntax of this program is so easy to learn. Generally speaking, it is a very good example for the rookie people working in the channel coding area.

Description: 无论是那种编码方式，在AWGN信道中的性能都明显由于在瑞利衰减信道中的性能。这一点也符合实际。毕竟AWGN信道是瑞利衰减信道的特殊情况。除此之外，在研究单一编码方式误码率时，样本帧数越大，则得到的误码率曲线就越平滑，较少出现较明显的凸起。(Either way, the performance in AWGN channel is obviously due to the performance in Rayleigh attenuation channel. This is also in line with reality. After all, AWGN channel is a special case of Rayleigh attenuation channel. In addition, the larger the number of sample frames, the smoother the BER curve will be, and less prominence will appear when studying the BER of a single encoding mode.)
