说明：  该程序给出了OFDM信号以及频谱分析，也插入了保护间隔(the procedure given OFDM signal and spectrum analysis, insert a protective partition)

说明：  corner提取 corner提取 corner提取(corner from corner from corner extraction)

很详细的协作频谱感知源程序，对比清晰，对初学者有很大的帮助，欢迎指正批评.(Very detailed cooperative spectrum sensing source, contrast is clear, there is a great help for beginners, please correct me criticism.)

说明：  对信号进行IQ处理，是获得复信号的一种手段。文件提供IQ同道处理程序(IQ processing of the signal, which is a means to obtain complex signal. File IQ fellow handler)

采用数字图像主分量分析（PCA）算法实现人脸识别（身份认证或分类）(Principal components using digital image analysis (PCA) algorithm for face recognition (identity or category))

该文件详细介绍了蚁群算法，不仅有代码，还有数据，并且还附带蚁群算法的介绍PPT，很有用的，是学习的好算法。(Ant colony algorithm was introduced in detail the file, not only the code, and data, and also with ant colony algorithm is introduced PPT, very useful, is good to learn algorithm.)

图像RGB颜色矩提取matlab程序，有注释,有需要的拿去(Image RGB color moments extraction procedures, there is a comment)

OFDM的16QAM调制与解调,有说明，有需要的朋友可以看看，个人著作(OFDM 16QAM)

我们对离散时间信号进行傅里叶变换和频谱分析。(We do the discrete time signal FFT and spectrum analysis )
