摘要：

The Hilbert-Huang transform is viewed as a promising method to process the nonlinear and non-stationary signal. However, it hasn't been a general method in signal processing due to its some deficiencies. In this paper, an algorithm is proposed to resolve one of its deficiencies that the EMD will generate redundant IMFs at the low-frequency region. This deficiency may cause misinterpretation to the result of processing signal. The experimental results show that the proposed algorithm successfully resolves this deficiency.
