Outage Probability Analysis of MF Precoded Massive MIMO with Multi-antenna User Environment

This paper expands the analytic formulation of single-cell multi-user massive multiple-input-multiple-output (MIMO) systems with matched-filter (MF) precoding into multiantenna user environments. Massive MIMO technologies are now remarkably evolving such as pre/post coding including beamforming strategies. Not only a base station (BS) having hundreds of antenna elements, but also user terminals (UTs) are also capable of array signal processing. It is enabled by implementation of array antennas in practical scale due to widespread millimeter wave band. Evaluating performance on massive MIMO systems where both BS and UTs have array antennas could impose impractical computation complexity. As an introduction of this challenge, this paper newly derives mathematical formulation of outage probability performance on MF precoded massive MIMO systems with multi-antenna user circumstance. Its consistency is confirmed by comparing the derived analytical model to the simulation results.
