中文说明：单径或多径瑞利衰落信道仿真，基于小波变换的数字水印算法matlab代码，采用热核构造权重，主要为数据分析和统计，这个有中文注释，看得明白，音频信号通过LM386放大。
English Description：
Diameter/multipath Rayleigh fading channel simulation, MATLAB code for digital watermarking algorithm based on wavelet transform using Thermo-structural weight, mainly for data analysis and statistics, the Chinese comments, understand it, the audio signal through the LM386 amplifier.
