说明：  常用的绘图命令及程序示例，包括基本绘图函数及调用，三维绘图命令。(Common example of drawing commands and procedures, including basic drawing functions and calls, three-dimensional drawing commands.)

这个Matlab程序是关于OFDM调制的。这里使用了BPSK调制，显示OFDM在误码率上的下降。(This Matlab program is about OFDM modulation. Here the use of BPSK modulation, show the OFDM at BER on the decline.)

In histogram equalization we are trying to maximize the image contrast by applying a gray level transform which tries to flatten the resulting histogram. The gray level transform is a scaled version of the original image s cumulative histogram. That is, the graylevel transform T is given by T[i] = (G-1)c(i), where G is the number of gray levels and c(i) is the normalized cumulative histogram of the original image.
