System bandwidth and the existence of generalized shift-invariant frames
Hartmut Führ, Jakob Lemvig
We consider the question whether, given a countable system of lattices in a locally compact abelian group , there exists a sequence of functions $(g_j)_{j \in…

Criteria for generalized translation-invariant frames
Jakob Lemvig, Jordy Timo van Velthoven
This paper provides new sufficient and necessary conditions for the frame property of generalized translation-invariant systems. The conditions are formulated in the Fourier domain…

On Wilson bases in L2(R^d)
Marcin Bownik, Mads Sielemann Jakobsen, Jakob Lemvig +1
A Wilson system is a collection of finite linear combinations of time frequency shifts of a square integrable function. In this paper we use the fact that a Wilson system is a shif…
