Applications of Wavelet Transform on Signals Catastrophe-points Detection
YE Zhi-chan · Computer and Modernization · 2008
According to the characters of wavelet transform auto-matchable Time-Frequency analysis,this paper proposes a new method to detect signals catastrophe-points by wavelet transform.At the beginning,the theories of wavelet transform and catastrophe-points detection are systematically stated.And then,the algorithm of catastrophe-points detection based on wavelet transform is proposed.
