WAVELET TRANSFORM(PART THREE) DYADIC WAVELET TRANSFORM AND SIGNAL SINGULARITY DETECTION
Xin Dong · RELAY · 1999
The property and algorithm of dyadic wavelet function and dyadic wavelet transform basing on B spline are introduced. Specially the theory of signal singularity detection basing on modulus maxima of wavelet transform is described. Its key point is that, the signal can be represented by the modulus maxima of wavelet transform and also can be reconsrtucted by the modulus maxima. Thus, signal representation becomes very clear. Because the dyadic wavelet transform possess translational invariability, it is widely used in mode identification and signal sigularity detection.
