| 摘 要： | 为了抑制MIMO干扰信道下的多小区干扰,采用子空间干扰抑制算法和功率分配相结合的干扰抑制方案,该方案充分利用系统总功率,将多小区干扰尽可能地重叠,以提高系统的性能.理论分析及仿真结果表明,与传统干扰抑制方案相比,该方案仅牺牲极微小的系统容量,却明显地降低了系统的干扰功率.

| Abstract: | In order to restrain multi-cell interference for MIMO interference channel,the authors adopted the combination of the interference suppression scheme about the subspace interference suppression algorithm and power allocation.This scheme fully utilizes the system’s total power,overlaps the multi-cell interference as far as possible,thereby to improve the system performance.Theory analysis and simulation results reveal that compared with the traditional interference suppression schemes,the proposed scheme is only at a small expense of system capacity,but obviously reduce the system interference power. |
