Abstract：Aiming at mode mixing of empirical mode decomposition (EMD) caused by the intermittency signal, a new method to eliminate mode mixing of EMD based on analytical mode decomposition, AMD, is proposed. In this method, taking advantage of instantaneous frequency characteristics of the first intrinsic mode function, IMF, the frequency components of IMF1 can be got, the bisecting frequency and the location of the intermittency signal. Then, AMD is used to extract the intermittency signal and decompose the processed signal by EMD method. Thus, the effect of the intermittency signal is eliminated. The results of simulation analysis and engineering application show that the proposed method can effectively eliminate mode mixing of EMD caused by intermittency signal.
