- Abstract:
- There are strong noise components in the vibration signal generated in ignition shock section during liquid rocket engine test. A Mallat algorithm based on wavelet transform is proposed in this paper for denoising of vibration signal. This denoising method was verified with the actual testing data. The obtained result is
