Type of the equiangular tight frames with (n+1) vectors in (R^n)

摘要

An equiangular tight frame (ETF) is a (d imes?n) matrix that has orthogonal rows and unit-norm columns. ETFs have applications in communications, coding theory and quantum computing. In this paper we investigate type of ETFs that have (n+1) vectors in (R^n). Also we state the connection between these frames with the complete graphs that containing (n+1) vertices.
