abstract = "Recently massive multi-input multi-output (MIMO) techniques have attracted growing research interest. However, most existing works assume centralized control, which may involve a heavy overhead as the number of users also becomes massive. In this paper, we focus on random-access massive MIMO systems. We first analyze the performances of two conventional schemes widely used in massive MIMO, and derive their closed-form expressions in the asymptotic case. Building on the latter, we maximize the system throughput through transmission control. To further exploit the potential benefit of massive MIMO techniques, we propose a novel multi-level transmission and grouped inter-ference cancellation (MLT-GIC) scheme, which can obtain a higher system throughput and provide a flexible tradeoff between throughput and complexity. Numerical results demonstrate the merits of the proposed scheme.",
