Weighted Fusion Frame Construction via Spectral Tetris
Peter G. Casazza, Jesse Peterson
Fusion frames consist of a sequence of subspaces from a Hilbert space and corresponding positive weights so that the sum of weighted orthogonal projections onto these subspaces is…
Spectral Tetris Fusion Frame Constructions
Peter G. Casazza, Matthew Fickus, Andreas Heinecke +2
Spectral tetris is a fexible and elementary method to construct unit norm frames with a given frame operator, having all of its eigenvalues greater than or equal to two. One import…
Optimally Sparse Frames
Peter G. Casazza, Andreas Heinecke, Felix Krahmer +1
Frames have established themselves as a means to derive redundant, yet stable decompositions of a signal for analysis or transmission, while also promoting sparse expansions. Howev…
