Unmanned aerial vehicle (UAV) communications are expected to play a major role in future
space-air-ground integrated networks (SAGINs). In this paper, a geometric three …

This paper proposes a non-stationary three-dimensional (3D) irregular-shaped geometry-
based stochastic model (IS-GBSM) for fifth generation (5G) and beyond massive multiple …

In order to provide reliable and efficient connections between unmanned aerial vehicles
(UAVs) and ground stations (GSs), realistic UAV-to-ground channel models are …

In this paper, a novel unmanned aerial vehicle (UAV) space-time-frequency (STF) non-
stationary channel model with time-space consistency for sixth generation (6G) massive …

The wireless communication systems based on Unmanned Aerial Vehicles (UAVs) have
found a wide range of applications recently. In this paper, we propose a new three …

We propose a 3-D elliptic-cylinder unmanned aerial vehicle (UAV) multiple-input-multiple-
output (MIMO) channel model for air-to-ground communication environments. The mobility …

In this paper, we propose a 3-D geometry-based stochastic model for multi-input multioutput
wideband nonstationary channels between the unmanned aerial vehicle (UAV) and the …

Unmanned aerial vehicle (UAV) communications have been considered as one of the
promising technologies to support numerous applications in the fifth and sixth generations …

A commonly used assumption in the existing unmanned aerial vehicle (UAV) channel
models is that the UAV flies along linear trajectories. However, this assumption does not …

In this article, the performance of UAV-based mmW links is investigated when UAVs are
equipped with square array antennas. The 3GPP antenna propagation patterns are used to …
