对由尺度函数g生成的L^2(R)上的多分辨分析以及小波空间Wo,我们给出由尺度函数g构造出Wo中的小波h的方法,建立了{h(x-k)}是Wo的Riesz基的充分必要条件,将程正兴等在尺度序列属于l′空间限制下得到的g和h的分解关系推广到l^2空间。
Suppose that a multi-resolution analysis on L^2(R) is produced by a scaling function g and Wo be a wavelet space. The method to construct a wavelet function h on Wo from the scaling function g is presented, and a sufficient and necessary condition for {h(x - k)} being a Riesz basis on Wo is proposed, then the decomposed relation of g and h introduced by Cheng for scaling sequences in 11 space is extended to scaling sequences in 12 space.
