论文摘要
本文提出了基于本文提出的,基于几何学和射线追踪(RT)理论,在本文中提出了无人驾驶飞机辅助(A2G)通信的无人驾驶汽车(UAV)辅助空中车辆(UAV)的参数计算方法。为了加快参数计算,开发了原始数字地图上场景数据库的重建过程。此外,通过在校园现场28 GHz的大量模拟来分析重建精度对通道参数和特征的影响。仿真和分析结果表明,简化的数据库最多可以节省50%的时间消耗。但是,在校园情景中,统计特性的差异很小。
Based on the geometry and ray tracing (RT) theory, a millimeter wave (mmWave) channel model and parameter computation method for unmanned aerial vehicle (UAV) assisted air-to-ground (A2G) communications are proposed in this paper. In order to speed up the parameter calculation, a reconstruction process of scene database on the original digital map is developed. Moreover, the effects of reconstruction accuracy on the channel parameter and characteristic are analyzed by extensive simulations at 28 GHz under the campus scene. The simulation and analysis results show that the simplified database can save up to 50% time consumption. However, the difference of statistical properties is slight in the campus scenario.
