A performance evaluation framework for LTE cellular networks with beamforming

In this paper, we investigate the practical evaluation of multiple-input multiple-output (MIMO) capabilities in latest generation cellular networks. The available rate region is analytically derived for 2 transmitter-receiver pairs, each with 2 transmit and 1 receive antennas, and integrated with an evaluation framework developed within the ns3 simulator. Finally, the resulting model is evaluated with a numerical campaign specifically referring to a system compliant with long term evolution (LTE) specifications. Our results not only confirm the validity of the analytical framework, but also quantify the margin between theoretical channel maximum rate and practically achievable throughput in LTE networks exploiting MIMO, and can be employed for integrated evaluations in practical contexts.
