文摘
- •
A jet engine vibration signal is denoised by an optimal new scheme.
- •
A new performance evaluation scheme for optimal selection of mother wavelet and thresholding method combination is proposed.
- •
Eighty four combinations of wavelet thresholding and mother wavelet are evaluated.
- •
Dmeyer mother wavelet combined with Rigorous SURE thresholding is introduced as the best combination.
- •
Inappropriate combination leads to data losing.
