A combined iterative interference alignment scheme for K-user MIMO interference channel

In this paper, utilizing the high performance of MAX-SINR and the low complexity of MIN-Leakage, a new combined iterative interference alignment scheme for K-user MIMO system is proposed to achieve a high channel capacity with low complexity. Moreover, because the iteration of MIN-Leakage and MAX-SINR can be decided independently, this proposed iterative scheme has a high flexibility to satisfy the requirements in different cases. The method of how to decide the iteration of these two processes is introduced in this paper and we show that our proposed scheme has a competitive performance based on the results of the simulation.
