用matlab仿真随机信号的调制解调，并绘制调制信号、已调信号、解调信号、输出信号的频谱、功率谱密度，自相关函数(Matlab simulation of random signals with modulation and demodulation, and draw the modulation signal, modulated signal, the demodulated signal, the output signal spectrum, power spectral density, autocorrelation function)

this is a matlab code

基于小波变换的数字音频水印算法 水印嵌入源程序 (With the rapid growth of computers, network and multimedia technologies, powerful and low cost computers allow people to easily create and copy digital products of multimedia. The Internet has made it easy to distribute the information at very low cost. However, these technologies also can be illegally copied, modified and redistributed multimedia data without regarding for intellectual property rights ownership. )
