对于给定的结构振动响应数据（时间序列信号）， 该程序可以分解成多个订单这些响应信号 小波子信号，然后计算出分信号能量spectum。 -For a given structural vibration response data (time series), the program can be decomposed into multiple sub-orders for the response signal wavelet signal, and then calculate

matlab在信号去噪过程中，运用小波包方法对信号进行降噪处理-matlab signal de-noising process, the use of the method of wavelet packet noise reduction processing on the signal

希尔伯特黄变换，可实现特征频率识别，里面有自带的原始数据(Hilbert yellow transform can realize characteristic frequency identification)
