Weak frames in Hilbert C*-modules with application in Gabor analysis
Damir Bakic
In the first part of the paper we describe the dual \ell^2(A)^{\prime} of the standard Hilbert C*-module \ell^2(A) over an arbitrary (not necessarily unital) C*-algebra A. When A i…
Expansions from frame coefficients with erasures
Ljiljana Arambasic, Damir Bakic
We propose a new approach to the problem of recovering signal from frame coefficients with erasures. Such problems arise naturally from applications where some of the coefficients…
On excesses of frames
Damir Bakić, Tomislav Berić
We show that any two frames in a separable Hilbert space that are dual to each other have the same excess. Some new relations for the analysis resp. synthesis operators of dual fra…
Finite extensions of Bessel sequences
Damir Bakić, Tomislav Berić
The paper studies finite extensions of Bessel sequences in infinite-dimensional Hilbert spaces. We provide a characterization of Bessel sequences that can be extended to frames by…
