fftshift 比较实数和复数傅里叶变换频谱的不同，以及N取值对其频谱特点的影响。(fftshift more real and complex Fourier transform spectrum of different, and the N values of the characteristics of its spectrum.)

小程序，用于识别图中整块的区域，画出它的内边缘和外边缘(Small procedures, used to identify the entire map of the region, draw the edge of its inner and outer edge of)

说明：  用MATLAB对一语音信号进行小波分解，然后对其各层系数进行处理以达到小波抑制的目的，重构处理后的信号，画出波形分析。(MATLAB to a voice signal wavelet decomposition, its floors coefficient then processed to achieve the purpose of inhibiting Wavelet, reconstruction after the signal waveform analysis paint.)

利用MATLAB实现时延的估计，所取的信号是带有一定信噪比的高斯白噪声(Delay Estimation Using MATLAB implementation, the signal is taken with a certain signal to noise ratio of the Gaussian white noise)

说明：  matlab的中文帮助文档，便于学习的好资料，欢迎大家下载。。。(matlab help documentation in Chinese, easy to learn any information, welcome to download. . .)

Correlation function

说明：  状态空间模型　加强ＭＡＴＬＡＢ学习　很有用的 (state-space model to strengthen MATLAB very useful learning)

3D Wave equation Model forwarding by the method of pesudo-spectrum

this is the selection diversity technique, used for avoiding the effects of fading.
