Empirical mode decomposition with wavelet de-noising

In order to solve the signal during transmission on the external mixture of noise, this paper presents the wavelet de-noising based on empirical mode decomposition (EMD), with Wu and others view that the previous order intrinsic mode function (IMF) components need for the wavelet de-noising, and with the wavelet threshold de-noising method and directly remove the high frequency components of EMD de-noising results compared, by using some objective criteria as the main criteria to evaluate the quality of signal recovery, the results show that the method of wavelet de-noising based on EMD is very effective and stable.
