Study on Wavelet Packet Denoising Technique and Its Application in Mechanical Fault Diagnosis

摘要

In this paper, the author introduces the principles of wavelet packet denoising, conducts a simulated analysis on the improved performance of wavelet packet denoising and develops the source Matlab program. In addition, the measured acoustic signals of seafloor sediments are denoised using wavelet packet. It is feasible to apply the wavelet packet denoising technique in a wide range of engineering testing fields involving denoising operation.
