Abstract

Abstract:

We investigate the interference alignment (IA) for the asymmetric MIMO multi-cell broadcast networks in the context of a square channel matrix. Specifically, for three different asymmetric scenarios, in order to design the precoding and decoding matrices, we propose the way to adopt the generalized eigenvalue decomposition (GEVD) based IA scheme. Furthermore, in order to maximize the achievable degrees of freedom (DoF), we formulate the problem as a linear programming (LP) problem which can be solved efficiently. It can be shown in simulation results that the maximum DoF obtained by the proposed GEVD IA assisted LP scheme is higher than that obtained by the existing scheme.

Key words: multi-cell, interference alignment, MIMO, generalized eigenvalue decomposition, linear programming
