Robust Lattice Alignment for $K$-User MIMO Interference Channels With Imperfect Channel Knowledge

Abstract

In this paper, we consider a robust lattice alignment design for K-user quasi-static multiple-input multiple-output (MIMO) interference channels with imperfect channel knowledge. With random Gaussian inputs, the conventional interference alignment (IA) method has the feasibility problem when the channel is quasi-static. On the other hand, structured… (More)
