MIMO Capacity and channel measurment

可以用来计算分歧度，这个分析度是信息论中的一个概念，类似于熵。(we can use it to calculate the klsym divergence)

用不同的算法解决BP网络的问题，十分强大，应有尽有。(use differnt ways to solve the BP network,powerful,convinient)

对于初学matlab 的人来说 ，这些小程序很基础，但是很有用，对以后大的程序有很大的帮助。(For beginners matlab people, these small program is very basic, but useful for future large program of great help.)

微波技术电子史密斯圆图程序Matlab---Smith-chart(Matlab---Smith-chart)

非线性SVM分类器，可以很好的将两类划分开(Non-linear SVM classifier, can be very good by the two open)

自相关函数在噪声检测,识别和有用信号的提取中的应用(autocorrelation function of the noise detection, identification and extraction of the useful signal of)

这里面有两个程序，两个都是采用4QAM调制。不过个人觉得第一个更容易懂，因为写的很有条理。我改的那个程序就是根据这个来的。 不过在这里面有个问题就是信道系数只能是由高到低，大家可以试试，改成[0.227 0.46 0.688 0.46 0.227]这个是老师给我的仿真中常用的信道系数，这个成为归一化信道，就是系数平方和为1. 第二个程序没有涉及到信道系数，但是这个程序当中，在128个子载波中，前后有32个空载波，这个在OFDM中也是经常用的，这样可以降低误码率。 (And there are two programs, two are based on 4QAM modulation. But personally feel that the first is easier, because the writing is organized. I changed that procedure is based on the past. However, there is a problem in that there is only channel coefficients from high to low, we can try and change into [0.227 0.46 0.688 0.46 0.227] This is the teacher gave me the simulation channel coefficient commonly used, this became normalized channel, is coefficient of the square and is 1. The second program is not related to channel coefficients, but this program which, in the 128 sub-carriers, the before and after the 32 air carriers, the in OFDM is also often used, which can reduce the error rate.)

用实数编码求盲均衡,包含一些测试代码，效果还不错(Demand with real-coded blind equalization, including some test code, the results were good)

PCA预测回归的一个例子，简单易懂 也有注释，导入数据注意格式即可使用(An example PCA regression forecasting, easy to understand but also notes, pay attention to the format to use to import data)
