Research of the Lifting Wavelet Arithmetic and Applied in Rotary Mechanic Fault Diagnosis

The lifting wavelet transform is completely based on the space-time area instead of relying on Fourier transform, so it can construct wavelet in non-shift area to achieve the separation of signal in different frequency bands. In this paper, the lifting scheme of wavelet and its multiphase expression...
