经验模态分解 小波变换 经验小波等信号处理方法，亲测可用(Empirical mode decomposition, wavelet transform, empirical wavelet and other signal processing methods, pro test can be used)

经验小波变换，将信号分解为多个子特征的子序列。性能较EMD、EEMD、WD等有所提升。(Empirical wavelet transform decomposes the signal into sub sequences of multiple sub features. The performance is improved compared with EMD, EEMD, WD and so on.)
