Second Order Statistics of Simulation Models for UAV-MIMO Ricean Fading Channels

Abstract

For the practical application and accurate analysis of unmanned aerial vehicle (UAV) multiple-input multiple-output (MIMO) communication systems, it is significant to propose corresponding simulation models for non-isotropic scattering UAV-MIMO channels. In this paper, we propose new deterministic and stochastic simulation models by using a two-cylinder reference model, where the signal is a superposition of line-of-sight (LoS) component, single-bounced (SB) rays, and double-bounced (DB) rays. Second order statistics of the simulation models have been compared to the reference model, including envelope level crossing rate (LCR), and average fade duration (AFD). The utility of our newly proposed simulation models is verified by the close agreement to the statistical features between theoretical and simulation results. Moreover, the developed stochastic simulation model has similar simulation complexity but performs better approximation than the deterministic model.
