Steiner equiangular tight frames

網頁2016年7月11日 · Abstract: An equiangular tight frame (ETF) is a set of equal norm vectors in a Euclidean space whose coherence is as small as possible, equaling the Welch … 網頁concept of optimally sparse frames was introduced in [9]. In addition, the infinite families of ETFs based on Steiner systems [12] are extremely sparse. In this paper, we propose a construction of sparse near-equiangular tight frames, which we re-fer to as Sparse

In more concrete mathematical terms, we consider a set of trace-normalized non-negative operators in a Hilbert-Schmidt ball of a given radius that maximize their mutual Hilbert-Schmidt distance. The radius of the ball bounds the …

網頁Steiner equiangular tight frames Janet Tremain 2012, Linear Algebra and its Applications Let F = {f n } N n=1 be a finite sequence of vectors in a real or complex M-dimensional Hilbert space H M . The corresponding frame operator is F F * = N n=1 f n f * n , where f * n denotes the linear functional that maps a given f ∈ H M to the scalar f, f n . 網頁An equal norm frame is a unit norm frame if c = 1. A Parseval (or tight) unit norm frame is an orthonormal basis; such a frame satisfies Parseval's identity. Equiangular frames A frame is an equiangular frame if there is a constant c such that , = for eachi j.
