Abstract: According to the quality of high-order statistics of the impact, a new method is presented to extract the feature of weak impact component hidden in the mechanical signal. The proposed method is based on blind deconvolution and wavelet soft-thresholding denoising method. Practically, using the presented method, the characteristics of weak impact component can be extracted well.

Key words: Feature extraction, Impact, Soft-thresholding denoising Blind deconvolution
