本程序主要对APSK信号进行了定性分析，对其星座进行优化设计，得出最佳设计。(the main procedures of APSK signal a qualitative analysis, Constellation optimize its design, The optimum design.)

基于C均值的多类模式识别，满足正态分布的样本进行分类训练。(Mean C-based multi-class pattern recognition, classification of samples to meet the normal training.)

傅里叶变换后频谱图 B：陷波函数作用后的频谱图 C：经逆变换的滤波后图像，效果不是很理想 Ifft2：为验证自己的快速傅里叶变换程序的正确性，用matlab自带逆变换程序将频谱逆变换后图形，与原图相符，说明快速傅里叶变换程序正确。(This is a FFT )

先用gabor 小波滤波器,做特征提取，然后用支持向量机（SVM）做分类，来实现人脸检测.需要用matlab 2010 或更新的版本才能运行(the code is used for face detection.Firstly it use gabor wavelet filter for feature extraction,Secondly it use support vector machine (SVM）for classification.matlab 2010 required.)
