论文摘要
实现各种无人驾驶汽车（UAV）系统的主要推动力之一是连接许多无人机和地面站的高性能通信系统。我们提出了具有低硬件复杂性的配备频谱有效的全双工方向性通信系统，以解决由面积通道中的共通道干扰引起的低光谱效率问题。在本文中，通过使用包括无人机和地面站的原型系统，进行现场实验，以确认所提出的系统的关键特征的可行性和有效性，即，通过方向天线和无人机的相对位置控制，无人机之间的共同通道干扰取消，而不是能量构成能量的自动化自我融合系统，传统的uavs in Forly-deflext formald forly-duc in Full-duc in Full-duc in Full-duc in Full-duc in Full-duc in Full-duc in Full-Duc in Full-duc in Full-duclext in Full-duc in Full deflext in Full-duc in Full-Duc中。上行链路和下行链路性能都经过测试。特别是，在下行链路实验中，当无人机处于不同的位置关系时，可以测量一对两个无人机之间的干扰能力。实验结果与设计非常吻合，并确认所提出的系统可以大大改善系统性能。
One of the key enablers for the realization of a variety of unmanned aerial vehicle (UAV)-based systems is the high-performance communication system linking many UAVs and ground station. We have proposed a spectrum-efficient full-duplex directional-antennas-equipped multi-UAV communication system with low hardware complexity to address the issues of low spectrum efficiency caused by co-channel interference in areal channels. In this paper, by using the prototype system including UAVs and ground station, field experiments are carried out to confirm the feasibility and effectiveness of the proposed system's key feature, i.e., co-channel interference cancellation among UAVs by directional antennas and UAV relative position control, instead of energy-consuming dedicated self-interference cancellers on UAVs in traditional full-duplex systems. Both uplink and downlink performance are tested. Specially, in downlink experiment, channel power of interference between a pair of two UAVs is measured when UAVs are in different positional relationships. The experiment results agree well with the designs and confirm that the proposed system can greatly improve the system performance.
