摘要:

本文给出了正交样条小波在信号奇异性检测中的应用,并且与其它常用的小波如Daubechies小波和双正交小波作了比较。实验表明,用正交样条小波进行信号奇异性检测不仅计算量小,而且效果好。

Abstract:

In this paper, we present the application of orthogonal spline wavelets in signal singularity detection, and make a comparison between the orthogonal spline wavelets and some common useful wavelets, such as the Daubechies wavelets and hiorthogonal wavelets. We also give some numerical results, which s how that the method is efficient.
