本文研究了在时域内小波的一种表达形式.利用正交规范化,获得了小波的有限差分表示.不仅该形式构造了任意次B样条正交小波.而且在时域中用来直接获得小波滤波器是有效的.
In this paper,we investigate a kind of representation of wavelets in time domain.Using the orthonormalization technique,we obtain a finite difference representation of wavelets.What's more,as a special case,we construct orthogonal B-spline wavelets of arbitrary order in this form.The result shows that this kind of representation used to obtain the wavelet filters directly is effective in time domain.
