On the capacity and simulation of 3-D MIMO mobile-to-mobile relay fading channels

This paper proposes a theoretical framework for the evaluation of the capacity of multiple-input multiple-output (MIMO) mobile-to-mobile (M-to-M) fading channels in dual-hop amplify-and-forward (AF) single-relay wireless communications networks. The evaluation is based on a recently introduced three-dimensional (3-D) geometry-based reference model for these channels. From this model, 3-D deterministic and statistical sum-of-sinusoids (SoS) based simulation models are also developed, under 3-D non-isotropic scattering conditions. The performance of the simulation models is verified through simulation results.
