Radon-Hurwitz Grassmannian codes
Matthew Fickus, Enrique Gomez-Leos, Joseph W. Iverson
Every equi-isoclinic tight fusion frame (EITFF) is a type of optimal code in a Grassmannian, consisting of subspaces of a finite-dimensional Hilbert space for which the smallest pr…
Harmonic Grassmannian codes
Matthew Fickus, Joseph W. Iverson, John Jasper +1
An equi-isoclinic tight fusion frame (EITFF) is a type of Grassmannian code, being a sequence of subspaces of a finite-dimensional Hilbert space of a given dimension with the prope…
Kirkman Equiangular Tight Frames and Codes
John Jasper, Dustin G. Mixon, Matthew Fickus
An equiangular tight frame (ETF) is a set of unit vectors in a Euclidean space whose coherence is as small as possible, equaling the Welch bound. Also known as Welch-bound-equality…
Phase retrieval with polarization
Boris Alexeev, Afonso S. Bandeira, Matthew Fickus +1
In many areas of imaging science, it is difficult to measure the phase of linear measurements. As such, one often wishes to reconstruct a signal from intensity measurements, that i…
Fingerprinting with Equiangular Tight Frames
Dustin G. Mixon, Christopher J. Quinn, Negar Kiyavash +1
Digital fingerprinting is a framework for marking media files, such as images, music, or movies, with user-specific signatures to deter illegal distribution. Multiple users can col…
Filter Bank Fusion Frames
Amina Chebira, Matthew Fickus, Dustin G. Mixon
In this paper we characterize and construct novel oversampled filter banks implementing fusion frames. A fusion frame is a sequence of orthogonal projection operators whose sum can…
