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。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 show that the method is efficient.
