Modeling of UAV MIMO Channel Model based on 3D Geometry

针对无人机的空地信道环境,提出一种空对地通信环境下的三维椭圆柱无人机多输入多输出信道模型。基于所提信道模型研究了发射机的移动性和高度,并且在考虑地面和路边环境反射的情况下研究了所提信道模型的统计特性。实验结果表明,所提模型的信道统计量与以往的通信信道结果一致。总体而言,由空间相关函数表示的所提信道模型为研究无人机信道通信系统提供了新颖且实用的方法。

Aiming at the air-to-ground channel environment of Unmanned Aerial Vehicle(UAV),this paper presents a Multi-Input Multiple-Output(MIMO)channel model for Three-Dimensional(3D)elliptical column UAV in air-to-ground communication environment.In this paper,the mobility and height of the transmitter are studied based on the proposed channel model.The statistical properties of the proposed channel model are studied by considering the reflection of the ground and roadside environments.Finally,the numerical results show that the proposed channel statistics are consistent with the previous communication channel results.The proposed channel model represented by spatial correlation function provides a novel and practical method for the study of UAV channel communication system.
