Study of Wavelet Decomposition and Wavelet Filterfor Pile Integrity Testing
Bai Qun · Journal of Wuhan Urban Construction Institute · 2005
Based on the theory of wavelet transform, the application of wavelet decomposition and wavelet filter for the signals of pile integrity testing is introduced. Combining with engineering examples, bior5.5 is chosen which is a wavelet base of biorthogonal series that are biorthogonal spline wavelet with linear phase. By comparing with the normal analysis methods, both advantages and defects of them are discussed.
