说明：  就是搭建的一个逆变器采用了CPS的控制方式(hvdc is good tool to analyse the function of the work)

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.)

一些关于MATLAB编写的空间插值法程序，对初学者有一定的帮助作用(About the spatial interpolation MATLAB program written for beginners with some helpful)

说明：  一个关于插值的例程，步骤详细，有详细的注释，对于通信专业的学习有用(An interpolation routine on the steps in detail, with detailed notes, learn useful for the communication professional)

Huffman encoding and decoding

本源码用MATLAB语言实现了自适应RLS算法，并附有FFT分析(rls fft)

GPS的CA码生成MATLAB程序，程序描述间接、明了(GPS generated MATLAB code of the CA procedure, the procedure described in indirect, to understand)

最大熵分割，成功调试过，可以完全实现最大熵分割，效果完美(Maximum Entropy Segmentation, successfully debugged Maximum Entropy Segmentation can be fully realized, the effect is perfect)

此段代买可以用来实现层次分析法，通过输入参数、更改参数，利用循环自动检验是否符合层次分析法的要求(solve the AHP problem)

多重比较LSD法实现方差分析的matlab代码，调用格式为输入A矩阵，每一列是一个因素水平，当重复数不相等时，缺失数据用nan补齐。输出参数为各均值的比较表。(Multiple variance analysis method to achieve more LSD matlab code, call format for the input A matrix, each column is a factor level, when the number of repetitions is not equal, nan filled with missing data. Output parameters for the mean comparison table.)
