matlab的时频分析工具包,还比较好用.希望对信号处理的时频分析有所帮助.(matlab the time-frequency analysis tool kit, is still relatively easy to use. wish to signal processing time-frequency analysis help.)

本代码包括经典的MMSE方法和LCMV方法的推导，并包括两种方法的仿真,很有用！(The code includes the derivation of the classical methods and LCMV MMSE method, and includes simulation of the two methods, very useful!)

相位重构用matalab编写的，感觉很不错，看看吧 (Written in phase reconstruction with matalab feels really good to see it)

本程序仿真了16QAM信号的载波相偏估计的HOS算法，整个算法实现分为（1）模拟发送端发送16QAM信号；（2）加入相偏来模拟通过信道后有相偏的测试信号；（3）利用HOS算法进行相偏估计与纠正；（4）输出星座图。(This procedure simulated a 16QAM signal carrier phase offset estimate of the HOS algorithm, the algorithm is divided into (1) analog transmitter to send 16QAM signal (2) by the inclusion of partial to simulate the channel after the phase offset of the test signal (3 ) algorithm using HOS phase offset estimate and correction (4) output constellation.)

基于PCA 和BP 神经网络的人脸识别方法是针对 PCA 方法中存在的高维数问题和它对未训 练过的样本识别率低的缺点而提出的。该方法在预处理的基础上，利用粗糙集对 PCA 降维处理后的人脸特征进行约简，提取其中分类能力强的特征，实现在识别精度不变的情况下，有效的去除冗余信息；然后将约简后的属性输入到神经网络进行规则提取，利用神经网络非线性映射和并行处理的特点，增强对人脸图像识别的泛化能力。实验证明，使用该方法在识别率上有一定的提高(Face recognition method based on PCA and BP Neural Network)

single phase tcr used for reactive power compensation in power transmission system.

说明：  很好用的matlab神经网络优化算法，值得下载。(Good use of the matlab neural network algorithm, it is worth downloading.)

ofdm系统源代码（包括qam调制、加噪、判决)(ofdm system modulation, noise, judgment)

1.采用C均值聚类算法对男女生样本数据中的身高、体重2个特征进行聚类分析，考察不同的类别初始值以及类别数对聚类结果的影响，并以友好的方式图示化结果。 2.采用分级聚类算法对男女生样本数据进行聚类分析。分别尝试采用身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征，以及身高，体重2个特征进行聚类，对比聚类结果，并以友好的方式图示化结果 (1. The use of C means clustering algorithm on sample data for boys and girls in the height, weight 2 characterized in cluster analysis to investigate the initial values of the different categories and the effect on the number of classes of the clustering result, and in a friendly way of illustration result. 2. Using hierarchical clustering algorithm to male and female students sample data clustering analysis. Try both using height, weight, like math, like literature, like sports, like pattern recognition feature a total of six, as well as height, weight, two features clustering, comparing clustering results, and in a friendly way of illustration of the results)

说明：  三维机织结构，根据平均化理论利用MATLAB实现编织结构弹性常数的预测，根据使用者输入参数不同，可求多种机织结构(Three-dimensional woven structure, according to the average theory using MATLAB to achieve the prediction of the elastic constants of woven structure, according to the user input parameters, can be different types of woven structure)
