New Deterministic and Stochastic Simulation Models for UAV-MIMO Ricean Fading Channels

Abstract

For the practical simulation and performance evaluation of unmanned aerial vehicle (UAV) multiple-input multiple-output (MIMO) Ricean fading channels, it is desirable to develop accurate UAV-MIMO channel simulation models for more realistic scenarios of non-isotropic scattering. In this study, using a two-cylinder reference model to describe the distribution of scatterers, we propose new deterministic and stochastic simulation models. Analytical and numerical results indicate that both simulation models provide good approximations to the desired statistical properties of the reference model, and the stochastic simulation model results in a better performance under comparable computational complexity.
