Asymptotic performance analysis of interference alignment under imperfect CSI

Abstract

Interference alignment (IA) is potentially able to deliver more than one degree of freedom (DoF) in wireless networks such that the achievable DoF can be linearly scaled up with the number of users. This improvement, however, comes at the cost of availability of perfect channel state information (CSI) which hinders the practical implementation of IA since… (More)
