通过选取初等旋转矩阵和初等反射矩阵,利用多分辨分析以及矩阵理论,给出了一种由已知紧支撑对称正交多小波构造具有相应性质多小波的方法.利用该方法还可以构造出一类平衡小波.最后,结合DGHM紧支撑对称正交多小波给出了具体的算例.
In this paper, a method is given to generate a new multi-wavelet with the corresponding properties from a compactly supported symmetric orthonormal multi-wavelet by choosing elementary rotation matrix and elementary reflection matrix. A class of balanced wavelets can also be constructed using this method. At last, the DGHM compactly supported symmetric orthogonal multi-wavelet is given in the method as an example.
