python 读取数据
TXT文件文件里的数据以多个空格隔开，并且不同变量间的空格数不同，读数据时容易出错，该程序可以将其正确读出(The data in the TXT file is separated by a number of spaces, and the number of spaces between different variables is different. It is easy to make mistakes when reading the data. The program can read it correctly.)

ofdm仿真
OFDM即正交频分复用技术，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)

[LDPC码]是LDPC码相关论文
[WuYuFei]中是WuYuFei的论文
[WuYufei_matlab]是WuYufei做Turbo码的Matlab程序
程序实现在固定信噪比和卷积长度的条件下，计算不同正常的帧错误概率和比特错误概率
turbo_sys_demo.m是主程序
其中trellis.m是构造网格的子程序
logmapo.m是LOGMAP译码算法子程序
sova0.m是SOVA译码算法子程序
encoderm.m是编码子程序
[22]是以WuYufei程序的改动，实现在帧长、信噪比和迭代次数固定的情况下，获得两个译码器的先验信息的变化情况
