FFT Filters provide precisely controlled low- and high-pass filtering (smoothing and sharpening, respectively) using a Butterworth characteristic. The image is converted into spatial frequencies using a Fast Fourier Transform, the appropriate filter is applied, and the image is converted back using an inverse FFT

一个低通滤波器的教学程序，可以观察低通滤波器的频域响应，有助于对低通滤波器有个了解(A low-pass filter teaching program, you can observe the frequency domain response of a low-pass filter, low pass filter helps to have an understanding)

tHIS MATLAB CODE SIMULATE RAYLEIGH MODEL USED IN WIRELESS COMMUNICATION SYSTEMS.Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communications channel) will vary randomly, or fade, according to a Rayleigh distribution.
