Equiangular tight frames with centroidal symmetry
Matthew Fickus, John Jasper, Dustin G. Mixon +2
An equiangular tight frame (ETF) is a set of unit vectors whose coherence achieves the Welch bound, and so is as incoherent as possible. Though they arise in many applications, onl…

Tables of the existence of equiangular tight frames
Matthew Fickus, Dustin G. Mixon
A Grassmannian frame is a collection of unit vectors which are optimally incoherent. To date, the vast majority of explicit Grassmannian frames are equiangular tight frames (ETFs).…
