说明：  一种基于噪声模板的 uwb 仿真 将训练序列进行叠加(noise )

说明：  直接转矩控制的研究，它是基于MATLAB7.01的(Direct Torque Control of the research, which is based on the MATLAB7.01)

matlab的FFT仿真文件，可以设置五种不同频率，幅值，初始想问的输入波形，并且通过FFT变换可以看到各个波形的频谱和相位。(The FFT simulation matlab file, you can set up five different frequency, amplitude, initial input waveform to ask, and you can see the spectrum and phase of each waveform by the FFT.)

先用butter filter去除噪音，再找到信号峰，对峰描叙的条件可以自行调整(butter filtering, and peak finding)

说明：  计算香浓信息熵，方便快捷的matlab代码，可以简单直接调用(Calculated Shannon information entropy, convenient matlab code can be simple and direct calls)

说明：  实现基频提取的RAPT算法（一种鲁棒性的基频提取算法）。输入文件为wav波形文件。(A Robust Algorithm for Pitch Tracking (RAPT))

Fuzzy Filter for Matlab Code

add a noise to a watermarked audio signal to test the robustness input : vector representing the watermarked audio file & the desired SNR output : vector representing the noisy watermarked audio file
