计算列向量的互信息，输入的向量不能为相同向量(Calculate vector mutual information)

《极品列车时刻表》- Need for Train Timetable

说明：  在原始正弦信号中加入线频干扰，后通过自适应陷波器输出，最后计算信号误差，程序可直接出图并有详细注释(The line frequency interference is added to the original sinusoidal signal, and then output by adaptive notch filter. Finally, the signal error is calculated. The program can be directly plotted with detailed notes)

实现MFC不规则对话框，一个漂亮的时钟计时器实例，-The realization of irregular MFC dialog box, and a beautiful example of the clock timer,

严格的说这并不是一个完整的程序，因为还需要配套硬件的支持。它是我上个假期去青岛给一个轮胎厂做缠绕机的时候做的。但是我觉得非常有必要把这个放出来，因为里面有一个我自己开发的控件，用于绘制工业曲线。压缩报里面还有我的实验记录呢。下载的同学请注意了，只学习，可别乱传播啊。不然让我老师知道我我死定了。-strictly speaking, this is not a complete set of procedures, as required supporting hardware support. It is my last holidays to Qingdao to a tire factory winding machine when done. But I think it is very necessary to have this released, because it is one of my own development controls for industrial drawing curves. There is also reportedly compressed my record? Experiment. Download the students to the only study, to be spread Instead ah. Otherwise I know my teachers I die.

基于WiFi 802.11a协议的无线通信系统的开发 端到端的802.11a的物理层，自适应调制，前向纠错码，ofdm传输，高斯白信道仿真 Viterbi解码等(End-to-end 802.11a physical layer * All mandatory and optional data rates: 6, 9, 12, 18, 24, 36, 48, and 54 Mb/s * BPSK, QPSK, 16-QAM, 64-QAM modulations * Forward error correction coding (convolutional; code rates 1/2, 2/3, 3/4) * OFDM transmission: 52 subcarriers, 4 pilots, 64-pt FFTs, circular prefix * Data interleaving * PLCP preamble (modeled as 2x2 long training sequences; see below) * Receiver equalization * Viterbi decoding * Data rates selectable on-the-fly * Adaptive modulation demo over dispersive multipath fading channel)

中国地面气候资料日值数据集(V3.0)处理程序，可以用来处理中国气象数据网上的气象数据(China surface climate data daily data set (V3.0) processing program can be used to process meteorological data on China Meteorological data online.)
