Abstract:

Unmanned Aerial Vehicles (UAVs) are considered as a promising platform providing high-speed wireless communica- tions services. In this paper, we propose a new three-dimensional (3D) non-stationary geometry-based stochastic channel model (GSCM) for the multi-input multi-output (MIMO) communica- tion links between the UAV and the mobile terminal (MT). The proposed GSCM considers not only the 3D scattering scenario, but also the 3D arbitrary trajectories and 3D antenna arrays of both terminals. The computation methods of time evolving channel parameters, i.e., path number, delays, powers and angle parameters, are also given. In addition, the theoretical statistical properties of the proposed GSCM, i.e., the autocorrelation func- tion (ACF), the cross-correlation function (CCF) and the Doppler power spectrum density (DPSD) are analyzed and derived. The good agreement between the simulated results and corresponding theoretical ones shows the correctness of both the simulation and the derivation.

I. Introduction

During the past decade, there has been a dramatic increase in the use of unmanned aerial vehicles (UAVs), i.e., the remote surveillance, filming, disaster relief, goods transport, and communication relaying, due to their affordable prices, multiple flight controls, high maneuverability, ease operability and increasing payload weight [1]. UAVs also have been considered as the aerial base station in the fifth generation (5G) communication systems [2], [3]. Since multi-input multi- output (MIMO) technologies can improve the capacity and efficiency of communication systems significantly, the UAV communication systems with MIMO technologies have gradu- ally become a research hotspot. However, it is vital to establish accurate and reliable UAV-MIMO channel models for the system design, optimization, and performance evaluation.
