A Novel Iterative Interference Alignment Scheme via Convex Optimization for the MIMO Interference Channel

In this paper, we propose a novel interference alignment (IA) scheme via convex optimization based on minimum mean square error criterion subject to individual transmit power constraints for the MIMO interference channel system. We show that transceiver under such criterion can be realized through an efficient iterative algorithm. The convergence of the proposed algorithm is discussed. Simulation results show that the proposed scheme outperforms the existing IA schemes with fast convergence.
