在本文中,我们研究了有限生成的移位不变空间 in 的结构。我们用其生成器与序列 in 的半离散卷积来表征移位不变空间 in 。此外,如果移位不变空间 in 的生成器是紧支持的,我们证明移位不变空间 in 是其生成器与序列 on 的半离散卷积形成的函数的交集和线性空间。
In this paper, we investigate the structure of finitely generated shift-invariant spaces in. We characterize shift-invariant spaces inin terms of the semi-discrete convolutions of their generators with sequences in. In addition, if the generators of shift-invariant spaces inare compactly supported, we prove that shift-invariant spaces inare the intersection ofand the linear space of functions formed with the semi-discrete convolutions of their generators with sequences on.
