Fault Signal Denosing Based Wavelet Transform

Le résumé fourni par la source

Due to the specialties of fault signals in missile fault diagnosis,traditional denoising methods will inevitably remove certain fault features,which adds to the difficulty of the later diagnosis.Accordingly,a novel denlising method applying wavelet analysis is presented in this paper.By considering the different propagating characters between signal and noise in wavelet domains,the fault signal SNR is greatly increased during denoising, which would prevent the loss of certain useful fault features.
