...EEMD To overcome the problem of mode mixing, EEMD was introduced based on the statistical properties of white noise, which showed that the EMD method is an effective self-adaptive dyadic filter bank when applied to the white noise, and the noise could help data analysis in the decomposition of EMD [49–51]....
