Periodic Nonuniform Dynamical Sampling in l(2)(Z) and Shift-Invariant Spaces

摘要

In his article, we mainly study the periodic nonuniform dynamical impling in l(2) (Z) and shift-invariant spaces. We first provide a sufficient and necessary condition for c is an element of l(2)(Z) which can be constructed by its spatial and temporal samples. Then we give a concrete example to show that the sufficient and necessary condition is feasible. Finally, we discuss the periodic nonuniform dynamic sampling problem in shift-invariant spaces.
