摘要
为了更好地消除MIMO干扰信道下的多小区干扰,该文采用子空间干扰对齐算法和功率分配相结合的干扰对齐方案,该方案充分利用干扰系统总功率,将多小区干扰尽可能地重叠在相应子空间内,以提高整体系统的性能.仿真结果显示,与传统干扰对齐算法相比,本算法仅以微小的系统容量为代价,却显著地降低了整体系统的干扰总功率。
In order to eliminate multi-cell interference for MIMO interference channel,in this paper,adopted the combination of the interference suppression scheme about the subspace interference alignment algorithm and power allocation,this scheme fully utilize the system’s total power,overlap the multi-cell interference as far as possible,thereby improving system perfor mance.Theory analysis and simulation results reveal that compared with the traditional interference suppression schemes,the pro posed scheme is only at a small expense of system capacity,obviously reduce the system interference power.
