Outage and Average Error Probability for UL-Massive MIMO Systems: Asymptotic Analysis

This paper investigates the asymptotic behaviour (error and outage probabilities) of a single cell multiple-input multiple-output (MIMO) system aided by a large scale antenna array. Specifically, the uplink transmission over composite fading channel with power-scaling scheme is considered. Where, most reported studies in this respect discuss the case of downlink scenario for convenience MIMO systems. Two assumptions are addressed: perfect channel information (CSI) and imperfect-CSI. In both cases, closed form expressions for error and outage probabilities in asymptotically large receive antenna environments are derived. Moreover, users' location impact on system performance is introduced. Numerical outcomes, validated by Monte-Carlo simulations, shed light on how different parameters and conditions can affect aforementioned performance metrics.
