psnr
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)

MultiCarrierDigitalCommunicationsTheoryandApplica
Multi-Carrier Digital Communications Theory and Applications of OFDM
Second Edition
Multi-carrier modulation‚ Orthogonal Frequency Division Multiplexing
(OFDM) particularly‚ has been successfully applied to
a wide variety of digital communications applications over the past
several years. Although OFDM has been chosen as the physical layer
standard for a diversity of important systems‚ the theory‚ algorithms‚
and implementation techniques remain subjects of current interest.
This is clear from the high volume of papers appearing in technical
journals and conferences.
Multi-carrier modulation continues to evolve rapidly. It is hoped
that this book will remain a valuable summary of the technology‚ providing
an understanding of new advances as well as the present core
technology.
