Phase retrieval from very few measurements
Matthew Fickus, Dustin G. Mixon, Aaron A. Nelson +1
In many applications, signals are measured according to a linear process, but the phases of these measurements are often unreliable or not available. To reconstruct the signal, one…
Necessary and sufficient conditions to perform Spectral Tetris
Peter Casazza, Andreas Heinecke, Keri Kornelson +2
Spectral Tetris has proved to be a powerful tool for constructing sparse equal norm Hilbert space frames. We introduce a new form of Spectral Tetris which works for non-equal norm…
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…
The Golden Ratio Encoder
I. Daubechies, C. S. Güntürk, Y. Wang +1
This paper proposes a novel Nyquist-rate analog-to-digital (A/D) conversion algorithm which achieves exponential accuracy in the bit-rate despite using imperfect components. The pr…
