MIMOSystem

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

近红外光谱小波变换预处理方法，能将信号分解成一系列小波函数的叠加，这些小波函数都是由一个亩小波函数平移和伸缩得到的。(Near infrared spectra pretreatment method, wavelet transform signal can be decomposed into a series of wavelet function, the wavelet function is a function by a mu wavelet translation and scaling. )
