大规模多输入多输出(MIMO)是一种新兴的移动通信技术，它在基站使用大量的天线来同时服务于多个容量非常大的单天线终端。在本文中，我们研究了利用大规模MIMO进行无人机通信的潜力和挑战。我们考虑多个单天线无人机同时与装备有大量天线的地面站(GS)通信的场景。具体地说，我们讨论了在视距(LOS)条件下可实现的上行链路(无人机到GS)的容量性能。我们还研究了为了保持GS和无人机之间的可靠通信链路而应该使用的天线极化类型。使用真实的几何模型得到的结果表明，大规模MIMO是大容量无人机网络的潜在使能器。
Massive multiple-input multiple-output (MIMO) is an emerging technology for mobile communications, where a large number of antennas are employed at the base station to simultaneously serve multiple single-antenna terminals with very high capacity. In this paper, we study the potentials and challenges of utilizing massive MIMO for unmanned aerial vehicles (UAVs) communication. We consider a scenario where multiple single-antenna UAVs simultaneously communicate with a ground station (GS) equipped with a large number of antennas. Specifically, we discuss the achievable uplink (UAV to GS) capacity performance in the case of line-of-sight (LoS) conditions. We also study the type of antenna polarization that should be used in order to maintain a reliable communication link between the GS and the UAVs. The results obtained using a realistic geometric model show that massive MIMO is a potential enabler for high-capacity UAV networks.
