Abstract

This paper synthetically analyzes and compares classical denoising methods, discussing their respective field of application, their denoising performance and influencing factors, etc. We summarize the advantages and disadvantages of these methods. Finally, vibration acceleration signal sampled on Diesel engine was de-noised by wavelet analysis and wavelet packet analysis, and its SNR(signal-noise-ratio) is enhanced to a satisfactory degree.
