摘要
高速移动场景是无人卫通的一种典型应用场景,也是一种极具技术难度的场景。针对高速移动场景下的无人卫通链路设计与性能优化问题,文中从链路预测、链路切换、链路保护和链路评估4个方面进行了研究,提出了一种综合考虑链路质量、资源利用率和切换代价的无人卫通链路切换方法。通过仿真实验和实际测试,验证了所提方法的有效性和优越性。
The high-speed mobile scenario is a typical application scenario of unmanned satellite communication,and it is also a scenario with great technical difficulty.Aiming at the design and performance optimization of unmanned satellite communication links in high-speed mobile scenarios,this paper studies link prediction,link handover,link protection and link evaluation,and proposes a link handover method for unmanned satellite communication that comprehensively considers link quality,resource utilization and handover cost.Through simulation experiments and practical tests,the effectiveness and superiority of the proposed method are verified.
