DFT implementation in MATLAB and ccs

说明：  一个Foxmail的辅助工具 SmartFox ，实现闪存“随身邮”功能，用来解决使用闪存时foxmail不提示已使用帐号的问题。(an auxiliary tool SmartFox achieve flash "Walkman Post" feature, intended to address the use of flash when I have not suggested the use of the account.)

在高斯背景下，测试在随机信号情况下的大特征值个数问题，并仿真了杂波功率谱(Gaussian background, test the number of large eigenvalues ​ ​ in the case of random signals, and simulate the noise power spectrum)

利用x(n)=Asin(pi*n/16)+z(n),z(n)为mean=0，var=0.1高斯白噪声，x(n)的SNR为10dB,s(n)=Asin(pi*n/16-5*pi),得出了x(n)和s(n)互相关函数r(n)，以及二者的卷积和.(The utilization for the mean of x (n) = Asin (pi* n/16)+ z (n), z (n) = 0, var = 0.1 Gaussian white noise, x (n) is the SNR as 10dB, s (n) =Asin (pi* n/16-5* pi), draw the x (n) and s (n) the cross-correlation function r (n), as well as the convolution of the two.)
