对分布式空域基站协作进行了分析仿真,重点对两小区场景和三小区场景采用最大化层虚拟信干噪比算法的预编码技术进行了仿真验证,并与采用最大化虚拟信干噪比算法的预编码技术进行了比对。仿真结果表明通过分布式的基站协作预编码算法,可以有效地抑制小区间干扰,提高系统的性能;结果还表明层虚拟信干噪比算法比虚拟信干噪比算法有更好的性能,增加天线数量也可以提高系统的性能。
This paper analyzes and simulates the cooperation of distributed airspace base station, and emphatically verifies the precoding technique of maximizing layer virtual SINR algorithm in two-cell scenario and three-cell scenario, and compares it with the maximized virtual SINR algorithm The precoding techniques were compared. The simulation results show that the distributed base station cooperative precoding algorithm can effectively suppress the inter-cell interference and improve the performance of the system. The results also show that the layer virtual SINR algorithm has better performance than the virtual SINR algorithm and increases The number of antennas can also improve system performance.
