这里提出了1种新的基站空域协作干扰抑制方案,该方案根据用户受到干扰的不同情况,动态地对相邻小区基站进行划分成簇。同时对所提出的方案在不同预编码算法和不同发送天线数目的条件下用Matlab软件进行仿真验证,其中,预编码算法的选择需要根据系统性能需求和实现的复杂度进行权衡。仿真结果表明所提出的动态协作簇小区间干扰抑制方案可以有效地抑制小区间干扰,同时大大地提高系统的性能。
Here, a new scheme of cooperative interference suppression of airspace in base stations is proposed. According to different situations in which users are interfered, this scheme dynamically partitions neighboring base stations into clusters. At the same time, the proposed scheme is verified by Matlab software under different pre-coding algorithms and different numbers of transmitting antennas. The selection of precoding algorithms needs to be weighed against the performance requirements and the complexity of implementation. The simulation results show that the proposed inter-cell interference suppression scheme of dynamic cooperative cluster can effectively suppress the inter-cell interference and greatly improve the performance of the system.
