A geometrical 3D multi-cluster mobile-to-mobile MIMO channel model with Rician correlated fading

Abstract

A three-dimensional (3D) stochastic model for multiple-input multiple-output (MIMO) channel based on geometrical signal propagation through a mixture of scattering clusters is proposed. A two-sphere layout along with Von Mises-Fisher (VMF) and cosine distribution laws is used to arrange the scattering environment, line of sight (LOS) option is also added. The model also includes optional cardioid or dipole pattern with possibility of free directivity setup for each element of multielement antenna (MEA) plus free moving vector setup for both transmitter (TX) and receiver (RX). Thus, the proposed model provides a lot of degrees of freedom for numeric simulation of mobile-to-mobile (M2M) link between high-speed altitudinal objects like unmanned aerial vehicles (UAV).
