说明：  此程序是运用music方法估计功率谱，并实现了信号还原。(This program adopts the mathod of music psd to estimate the powerdensity,and get the original signal.)

说明：  一个OFDM信号产生以及解调程序，用matlab编写(OFDMmatlab)

Bradley local image thresholding The brief idea of the algorithm is that every image s pixel is set to black if its brightness is T percent lower than the average brightness of the surrounding pixels in the window of the specified size, otherwise it is set to white.
