代码是一种数据挖掘算法，fuzzy-K-means，对数据进行分类(The code is a data mining algorithms, fuzzy-K-means, data classification)

是CDMA仿真系统产生，很多都讲倒了要仔细查阅的(CDMA is generated simulation system, many say it upside down to the detailed inspection)

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.
