论文摘要
无人驾驶飞机（UAV）中波束形成的使用可能会显着提高空对接地链路质量。本文介绍了这种基于无人机的光束系统在实时蜂窝网络上的实验试验的结果。已经为实验构建了带有定向天线的测试床。结果表明，波束形成可以扩展由于天线增益而扩大信号覆盖范围，并在空间上减少干扰，从而导致更高的信号质量。此外，它通过减少切换事件对飞行无人机的移动性能产生积极影响。还讨论了，在这种情况下，应将束缚转换为上行链路吞吐量增益。
The usage of beamforming in Unmanned Aerial Vehicles (UAVs) has the potential of significantly improving the air-to-ground link quality. This paper presents the outcome of experimental trial of such a UAV-based beamforming system over live cellular networks. A testbed with directional antennas has been built for the experiments. It is shown that beamforming can extend the signal coverage due to antenna gain, as well as spatially reduce interference leading to higher signal quality. Moreover, it has a positive impact on the mobility performance of a flying UAV by reducing handover occurrences. It is also discussed, in which situations beamforming should translate into the uplink throughput gain.
