64天线双极化圆柱阵空对地定向通道测深仪
Air-to-Ground Directional Channel Sounder With 64-antenna Dual-polarized Cylindrical Array
摘要：
无人驾驶飞行器（UAV），通常称为无人机，是未来无线通信的重要组成部分，无论是作为需要与地面站通信的用户设备，还是作为3D网络中的基站。为了分析“有用的”链路和调查对其他地面节点的可能干扰，需要了解空对地信道。由于地面节点通常配备有天线阵列，信道调查需要考虑它，本研究提出了一个大规模多输入多输出基于我们的实验室最近开发的空对地信道探测器，它可以执行上述要求的测量。在概述了探测器的原理和功能后，我们提出了演示功能的样本测量，并首次深入了解城市环境中的空对地大规模多输入多输出信道。我们的研究结果提供了一个平台，未来的调查和可能的增强大规模多输入多输出系统。
英文摘要：
Unmanned Aerial Vehicles (UAVs), popularly called drones, are an important part of future wireless communications, either as user equipment that needs communication with a ground station, or as base station in a 3D network. For both the analysis of the "useful" links, and for investigation of possible interference to other ground-based nodes, an understanding of the air-to-ground channel is required. Since ground-based nodes often are equipped with antenna arrays, the channel investigations need to account for it. This study presents a massive MIMO-based air-to-ground channel sounder we have recently developed in our lab, which can perform measurements for the aforementioned requirements. After outlining the principle and functionality of the sounder, we present sample measurements that demonstrate the capabilities, and give first insights into air-to-ground massive MIMO channels in an urban environment. Our results provide a platform for future investigations and possible enhancements of massive MIMO systems.
