The Complementary EEMD is used to decompose the signal on a multiple components.

The CEEMD not only overcomes the mode mixing, but also eliminates the residual of added white noise and enhance the calculation efficiency of the EEMD method.

A new method for choosing automatically the relevant IMFs is introduced.

A new A new method called FWEO is presented to demodulate the reconstructed signal.

Moreover its simplicity and computational efficiency, the FWEO method is able to detect signal impulsiveness without any pre-filtering process.
