摘要：
This paper considers communications and network systems whose properties are characterized by the gaps of the leading eigenvalues of[inline-graphic not available: see fulltext] for a matrix[inline-graphic not available: see fulltext]. It is shown that a sufficient and necessary condition for a large eigen-gap is that[inline-graphic not available: see fulltext] 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.
