Weaving Information Packets

Ole Christensen, Hong Oh Kim, Rae Young Kim

The concept of weaving of frames for Hilbert spaces was introduced by Bemrose et al. in 2016. Two frames ${f_{k}}_{k \in I}, {g_{k}}_{k \in I}$ are woven if the ``mixed system" $\{f_…

A survey on frame representations via dynamical sampling

Ole Christensen, Marzieh Hasannasab

Dynamical sampling deals with representations of a frame ${f_{k}}_{k = 1}^{\infty}$ as an orbit ${T^{n} φ}_{n = 0}^{\infty}$ of a linear and possibly bounded operator $T$ acting on the…

Explicit constructions and properties of generalized shift-invariant systems in $L^{2} (R)$

Ole Christensen, Marzieh Hasannasab, Jakob Lemvig

Generalized shift-invariant (GSI) systems, originally introduced by Hernández, Labate & Weiss and Ron & Shen, provide a common frame work for analysis of Gabor systems, wavelet sys…
