this file has codes that describes how to ccmpute the signal spectrum , the power spectrum, how to calculate the autocorrelation sequence of a signal, how to calculate the autoregressive coeffecients of a signal,and how to reduce the noisy elements in a speech sample.

介绍matlab程序中的傅里叶变换测试语音，测试语音的频谱，并改变采样率和采样点，在测试语音(Matlab program introduces test Fourier transform voice, test speech spectrum, and change the sampling rate and sampling points, the test speech)

本程序包里面代码用matlab编写，有三个demo，分别处理然后用CS重建1维，2维信号，最后一个是对大脑图像做CS重建对比(This package inside the code written in matlab, there are three the demo, be treated separately and then use the CS reconstruction of one-dimensional, two-dimensional signal, the last CS reconstruction compared brain images)

本文件描述了OFDM的频谱示意图，并给出了单载波和多载波情况下的频谱比较，以及源码(OFDM spectrum schematic)

快速傅里叶变换的子程序，直接在主函数中调用即可直接绘制信号的频谱图。(The subroutine of the fast Fourier transform can directly draw the spectrum of the signal by calling it directly in the main function.)

matlab写的蛇形算法，效果很好，内附图片，通过改变输入的图像运行自己的程序。( snake algorithm with matlab , works well.)
