Abstract :
In this paper we propose a Signal-to-Interference Ratio (SIR) based grouping scheme of interference alignment (IA) in order to increase the sum-capacity for K-user multiple-input multiple-output (MIMO) interference channel. As a feasibility proof of this scheme, two IA groups in a simple road environment model are considered and the achievable sum-capacity is evaluated.
