Advances in Computational Mathematics, 2013 We introduce a class of finite tight frames called prime tight frames and prove some of their elementary properties. In particular, we show that any finite tight frame can be written as a union of prime tight frames.

Journal of Fourier Analysis and Applications, 2011 We introduce probabilistic frames to study finite frames whose elements are chosen at random. While finite tight frames generalize orthonormal bases by allowing redundancy, independent, uniformly distributed points on the sphere approximately form a ...

Continuous Shearlet Tight Frames [PDF]
Journal of Fourier Analysis and Applications, 2010 Based on the shearlet transform we present a general construction of continuous tight frames for $L^2(\mathbb{R}^2)$ from any sufficiently smooth function with anisotropic moments.

Tremain equiangular tight frames [PDF]
Journal of Combinatorial Theory, Series A, 2017 Equiangular tight frames provide optimal packings of lines through the origin. We combine Steiner triple systems with Hadamard matrices to produce a new infinite family of equiangular tight frames.

Construction ofk-Angle Tight Frames
Numerical Functional Analysis and Optimization, 2016 Frames have become standard tools in signal processing due to their robustness to transmission errors and their resilience to noise. Equiangular tight frames (ETFs) are particularly useful and have been shown to be optimal for transmission under a ...

Constructing tight fusion frames
Applied and Computational Harmonic Analysis, 2011 A tight fusion frame is a sequence of orthogonal projection operators that sum to a scalar multiple of the identity operator. The authors resolve the question of existence of such frames in the special case where the underlying space is finite-dimensional and the fusion frame's subspaces have equal dimension.

Tight Reference Frame–Independent Quantum Teleportation [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 We give a tight scheme for teleporting a quantum state between two parties whose reference frames are misaligned by an action of a finite symmetry group.

Constructions of biangular tight frames and their relationships with equiangular tight frames
, 2017 We study several interesting examples of Biangular Tight Frames (BTFs) - basis-like sets of unit vectors admitting exactly two distinct frame angles (ie, pairwise absolute inner products) - and examine their relationships with Equiangular Tight Frames ...
