Impact of MIMO channel models on outage capacity

The comparison of the outage capacity for multiple-input multiple-output (MIMO) channel models that are based on different channel models is made. For this comparison, we chose the 3GPP Spatial Channel Model (SCM), a METRA Analytical Spatial Channel Model (A-SCM), and the correlation-based Long Term Evolution channel model (LTE). The effects of antenna element separation, array orientation, angle spread, and mutual coupling are compared for the models. The SCM performance showed the best agreement with how measurement results from the literature depend on the parameters studied, followed by the A-SCM and then the LTE model. The SCM was also the most computationally involved, followed by the A-SCM, and then the LTE models. We also discuss in what situations a particular channel model could be advantageous.
