this matlab code denoise the pink noise from pcg signal and generate the specogram

pq控制，恒功率控制，在微网中有一定的使用价值(pq control, constant power control, there is a certain value in the micro network)

几个有关通信系统的matlab程序,有关信号，包含：a,对抽样频率为90kHz的信号进行下抽样抗混叠滤波器设计的程序，b,信号抽样率转换的程序，c,通过补零内插对信号进行下抽样，分析抽样对信号频谱的影响的程序(Some matlab programs about communiction system,mainly about signal,a,program about filter to signal sampling without aliasing ,b,transfering signal sampling rate,c,zeros-added sampling,with its influence of phase-frequency。)

整数小波变换与图像压缩 用MatLAB实现图像的整数小波变换，对行和列各做一次。采用最简单的S小波，它是Haar变换的整数形式。(integral wavelet transform and image compression .To realize the integral wavelet transform based on the Matlab in rows and columns. Using the simple S wavelet ,which is integral form of the Haar transform)

基于傅里叶变换的混沌图像置乱加密方法及其代码实现(Fourier transform based on chaotic image encryption and scrambling code implementation)

小波包4级分解及特征向量空间的建立，希望对大家有用(4 wavelet packet decomposition and feature vector space for the establishment, in the hope that useful to everybody)

重要的Contourlet资料，有程序，有论文，很全面(Contourlet important information, there are procedures, papers, very comprehensive)

说明：  读取图像lena.tif，进行DCT变换，每个图像块保留10个DCT系数进行重构图像，比较重建图像与原始图像的差异。(Read the image lena.tif, the DCT transform, each image block of 10 DCT coefficients to retain the reconstructed image, reconstructed image compared with the original image differences.)

说明：  matlab的源程序，是很重要的补充，大家可以下载(matlab source, it is important to add that you can download)
