摘　　要：为了提高战术数据链地面站点的上行覆盖能力,将多点协作技术应用于战术数据链系统,在给出多点协作模型的基础上,提出了一种基于信号干扰噪声比(SINR)的数据检测算法。该模型利用多个站点之间的空间分集增益,提高边缘数据链终端的信号检测质量,从而提高了地面站点的上行覆盖性能。仿真结果表明,该多点协作模型在较低系统复杂度增加的前提下大大提高了地面站点的边缘吞吐量和上行覆盖能力。In order to improve the up-link coverage capacity of tactical data link in the ground sites,this paper applies the coordinated multi-point technology to tactical data link system,brings forward a data detection algorithm based on signal to interference and noise ratio（SINR）on the basis of giving coordinated multi-point model.The model uses the space diversity gain among multiple sites to advance the signal detection quality of edge data terminal,thereby improves the up-link coverage capacity of the ground sites.The simulation results show that the edge throughput and up-link coverage capacity of ground sites can be improved greatly by using the coordinated multipoint model under the premise of system complexity increasing relatively low.
