对数据进行EMD分析时，如果数据不是纯的白噪声,则分析过程中一些尺度将会丢失,出现模态混叠现象。EEMD通过附加均匀分布 在整个时频空间的白噪声，可有效抑制这种现象的发生。(EEMD is insufficient for the EMD method, we propose a noise-assisted data analysis methods. EEMD decomposition principle is: when the additional white noise uniformly distributed throughout the time-frequency space, the time-frequency space is carved up by the filter component of the composition at different scales.-)
