混沌信号经过EMD分解，得到的IMF序列，求每个IMF序列与原始序列的互相关系数(The chaotic signal is decomposed by EMD to obtain the IMF sequence, and the cross-correlation coefficients between each IMF sequence and the original sequence are calculated)

计算emd分量的能量熵；imf与原信号的相关系数(The energy entropy of calculating the EMD component)

Emd分解，通过峭度和相关系数选择IMF，进行信号重构，小波分解，小波包分解。(Emd decomposition, selecting IMF by kurtosis and correlation coefficient, signal reconstruction, wavelet decomposition, wavelet packet decomposition.)
