Simulation models for MIMO mobile-to-mobile channels

Two new sum-of-sinusoids (SoS) based simulation models for multi-input multi-output (MIMO) mobile-tomobile (M-to-M) Rayleigh fading channels are proposed. First, an ergodic statistical (deterministic) SoS simulation model is proposed, and its statistical properties are derived and verified by simulations. The deterministic model is shown to well approximate the reference model and, compared to existing simulation models, requires smaller number of scatterers. By allowing all three parameter sets (amplitudes, phases, and Doppler frequencies) to be random variables, the deterministic model is modified to yield a statistical simulation model. Compared to the deterministic and existing simulation models, the statistical model better matches the reference model over a wider range of normalized time delays while using a smaller number of scatterers.
