wave_denoise
此程序仿真了一个被污染了的信号源,然后通过小波去噪,成功取出了信号中的杂波(This procedure simulation has polluted the supply oscillator, then through the wavelet denoising, the success took out in the signal clutter )

decomposition
运行emd,得到输入信号X的固有模态函数(imf),每列代表着信号X的一阶分量,X就是我们采集的信号。
hhtdn是hht去噪的程序,可以不看,仅看emd 和 findpeaks
wvtdn是wavelet去噪程序,如果只是分解信号,仅用下面的语句即可
[C,L] = wavedec(x_noise,dl,wn);
x_noise就是我们采集的信号,dl是分解的阶数,wn是分解的母小波名称(% Empiricial Mode Decomposition (Hilbert-Huang Transform)
% imf = emd(x)
% Func : findpeaks)
