PCA

说明：  设计一个2FSK数字调制系统，要求： （1）设计出规定的数字通信系统的结构； （2）根据通信原理，设计出各个模块的参数（例如码速率，滤波器的截止 频率等）； （3）用Matlab或SystemView 实现该数字通信系统； （4）观察仿真并进行波形分析； （5）系统的性能评价。 (Design a digital modulation system 2FSK require: (1) design a digital communication system under the structure (2) According to the communication theory, design parameters of each module (such as code rate, filter cutoff frequency, etc.) (3 ) with Matlab or SystemView realize the digital communication system (4) observing the waveform simulation and analysis (5) system performance evaluation.)

说明：  ANN-BP分类器设计，用其中一半的数据采用ANN-BP算法设计分类器，另一半数据用于测试分类器性能。(ANN-BP classifier design, with half of the data using ANN-BP algorithm design classifier, the other half of the data used to test the classifier performance.)

实现了EM算法对高斯混合模型进行聚类，并将聚类结果用图像展示出来，希望对混合模型的朋友有用。(The EM algorithm is implemented to cluster the Gauss mixture model, and the clustering results are displayed with images, hoping to be useful to friends of the mixed models.)

基于卡尔曼滤波的MATLAB 扩展程序，可以供大家参考下(Kalman filter-based MATLAB extension, for your reference)

this is a game which is very simple,
