Simplified simulator for correlation-based MIMO radio channel model

The principal goal of this paper is to provide a simplified and efficient MIMO radio channel simulator based on the most popular correlation-based MIMO radio channel model and the SoS approach which is traditionally used for generation Rayleigh fading waveforms with temporal correlation. First an improved simulation model for the generation of multiple Rayleigh fading waveforms is proposed, which is both simple and efficient with rapid convergence speed. Next a simplified spatial correlation model of outdoor BS is introduced in closed-form expression. This approach has negligible difference compared to the reference correlation values. In the end, capacity of the simulated MIMO radio channel is evaluated with respect to different AOA. The presented simulator is suitable for the theoretical analyses of MIMO radio systems and dynamic MIMO channel simulation.
