一种基于小波变换的灰度数字水印嵌入算法,使用matlab实现，含有原始论文。不过不是很理想，希望大家改进(Gray-scale based on wavelet transform digital watermark embedding algorithm, using matlab implementation, containing the original papers. But not very good, hope that we improve the)

正弦函数用fft实现的单边振幅谱图形(未加噪声）(Unilateral amplitude of the sine function with fft spectrum graphics)

2元BPSK调制加高斯信道硬判决统计误码率(2 yuan plus Gaussian channel BPSK modulation hard decision error rate statistics)

这是我自己写的亲测可用的matlab 牛顿迭代法函数程序(This is the Newton iteration program based on MATLAB written by myself)

This simulation plots the Effective SNR of and OFDM as a function of Output Power Backoff from 0 to 9.5 dB, for three different number of carriers.

the equivalent of Zhou Wang s SSIM matlab code //with K1 = 0.01, K2 = 0.03 and windows = ones(8) since this enables a fast implementation using summed area tables. //the measure is described in "Image quality assessment: From error measurement to structural similarity" //was originally adapted from the matlab code for the universal image quality index
