说明：  对数正态分布的杂波程序 比较经典的有所改动(Lognormal distribution of the clutter classic procedure is subject to change)

It randomizes the order of vectors within the matrices

测试波束成形的相位是否一致,测试结果说明了问题。(Test the phase of beamforming are same or not.the results are proved to be right.)

this is a harr classifier for frontal face

灰色预测方法的特点表现在：首先是它把离散数据视为连续变量在其变化过程中所取的离散值，从而可利用微分方程式处理数据；而不直接使用原始数据而是由它产生累加生成数，对生成数列使用微分方程模型。这样，可以抵消大部分随机误差，显示出规律性。(The characteristics of the grey prediction method are as follows: First, it regards the discrete data as the discrete value of the continuous variable in its change process, so that the differential equation can be used to process the data; instead of using the original data directly, it generates the cumulative generation. Number, using a differential equation model for generating a series. In this way, most of the random errors can be offset, showing regularity.)

THIS M-FILE USES THE TRANFER MATRIX METHOD TO EVALUATE THE COUPLED-MODE EQUATIONS. THE REFLECTION SPECTRUM OF THE GRATING AND THE TRANSMISSION SPECTRUM, DELAY AND DISPERSION OF THE FABRY-PEROT FILTER ARE SIMULATED

文件夹“AWGN”说明了系统误码率在均衡前后随SNR增加的变化。 （1）绘制误码率曲线。运行m文件：main_picture,调用主函数：ofdm_AWGN。 （2）绘制星座点图。运行m文件：snr_xinzuotu(Folder )

说明：  演示方向图乘积定理，可以让你清晰地看明白成绩定理的过程(yan shi fang ixang tu cheng ji ding li)
