对信号进行小波分解，用硬阈值方法去除噪声，进而提高精度-right signal wavelet decomposition, with a hard threshold to remove noise, and to improve accuracy

正弦信号加白噪信号，对叠加信号进行延拓并进行一维小波分解，重构逼近信号和细节信号并显示。-Sinusoidal signal with white noise signal, superimposed signals of continuation and the one-dimensional wavelet decomposition and reconstruction approximation signal and detail signal and displayed.

emd工具箱，用经验模态分解时一定要安装的工具箱，解压后添加进toolbox里，setpath后，记得更新工具箱，就可以使用了，我是用来分解信号进行信号处理的-emd toolbox with a time of empirical mode decomposition must install kit, unpacked add toolbox, the post setpath, remember to update the toolbox, you can use, and I was u

奇异谱分解技术，与相空间重构相结合，对信号进行降噪处理-Singular spectrum analysis technology, combined with the phase space reconstruction of signal noise reduction
