三种随机构造法：Gallager_getH、Mackay_getH、PEG_getH(Three random construction methods: Gallager_getH, Mackay_getH, PEG_getH)

a good OFDM QAM16 simulation for matlab program

在matlab下，基于循环前缀的仿真验证源代码，比较详细(In matlab, the simulation based on cyclic prefix for the source code, more detailed)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

这是整套的ldpc-ofdm仿真模拟代码，可以运行的，输出的是误码率图像(This is the whole set of ldpc-ofdm simulation code, you can run the output image is the bit error rate)

说明：  m序列的生成，包括在有限域GF(p)中的基于不同p取值，不同级数条件下的本原多项式多种选择条件下的m序列生成。(m sequence generation, including in GF (p), the p value based on different, different levels under the conditions of primitive polynomial number of options under the conditions of m-sequences generated.)

易语言http断点续传源码 ,很不错的易语言源码,适合易语言爱好者学习,()

信息通过LDPC编解码误码率与未编码信息误码率比较(Comparison of BER between uncoded information and LDPC code)

This program generates BPSK signal waveforms and plot the power spectrum of unfiltered BPSK.

说明：  伪随机LED灯，实现八位LED灯的随机闪烁以及其它的控制。(Pseudo-random LED lamp)
