A Hub Matrix Theory and Applications to Wireless Communications

Abstract

This paper considers communications and network systems whose properties are characterized by the gaps of the leading eigenvalues of for a matrix. It is shown that a sufficient and necessary condition for a large eigen-gap is that is a "hub" matrix in the sense that it has dominant columns. Some applications of this hub theory in multiple-input and multiple-output (MIMO) wireless systems are presented.
