function PSNR2 = psnr(I,I_iter) 计算峰值信噪比 I : 原始信号 I_iter : 加噪信号(function PSNR2 = psnr (I, I_iter) calculate the peak signal to noise ratio I: the original signal I_iter: adding noise signal)

说明：  这是一个超宽带PPM接收机的程序，用于接收超宽带信号，是用MATLAB编程的(This is an ultra-wideband PPM receiver procedures for receiving ultra-wideband signals,and it is programmed MATLAB )

自己按照TPAMI文章编写的approximate pairwise accuracy criterion (aPAC)。已测试无误，并提供该代码所对应的文章。(This matlab code is writtern by myself,namely approximate pairwise accuracy criterion (aPAC)。The paper corrsponding to code is also provided.)
