摘要 讨论了L(2R)平移不变子空间中基于框架的非整点抽样定理,得到了抽样函数在频域中的表示形式以及非整点抽样定理在L(2R)平移不变子空间中成立的充要条件. In this article, a lattice sampling theorem for frames in translation-invariant subspace of L^2(R) is discussed. Moreover, a formula of the lattice sampling functions in frequency space and a necessary and sufficient condition of the lattice sampling theorem in translation-invariant subspace of L^2(R) are derived.
