摘要
在Hilbert空间中,引入了小波算子对、多尺度分析(MRA)、正交小波向量、尺度向量、酉移位算子的概念。
In a Hilbert space,some concepts, such as multiresolution analysis(MRA),orthogonal wavelet vector,scaling vector,unitary shift operator, are introduced,the existence of the scaling vector and orthogonal waveletvector are proved,and the standard forms of them are also given.
