Interference alignment (IA) is a technique shown to be able to achieve a significant overall throughput in a 𝐾-user multiple-input multiple-output (MIMO) interference channel (IC). In this paper, we try to modify the conventional IA designs to achieve enhanced sum-rate performance. We jointly design transmit and receive IA filters (precoding and suppression filters) at a central unit (CU) to reduce the channel state information (CSI) feedback/sharing overhead. At the CU, in a one-way iterative strategy (left ?L? to right ?R?, see Fig. 1), the precoding filters are optimized (on side ?L?) in the direction of the gradient of the sum-rate, and the suppression filters are chosen (on side ?R?) to minimize the leakage interferences. Then, in a two-way iterative strategy, the proposed scheme alternates between ?L? and ?R? sides to design the IA filters through the joint sum-rate maximization and interference leakage minimization on each side. Finally, a modified version of the two-way iterative strategy is proposed to design the IA filters on the basis of signal-to-interference-plus-noise ratio (SINR) (instead of the interference minimization) and the sum-rate maximization techniques. |
