Analysis of MRT Precoding Massive MIMO for Railway & Maritime Terminal in Multi-cell Environment

This paper extends downlink multi-user massive multiple-input-multiple-output (MIMO) with maximum ratio transmission (MRT) precoding for rapidly movable railway and maritime terminal in multi-cell environment and analyzes its outage probability. In a railway & maritime adjacent multi-cell environment, especially for users (regarded as railway train or ship terminal) at the cell edge, inter-cell interference (ICI) causes the performance degradation of communication quality. Therefore, it is necessary to establish an analytical model to consider the above-mentioned problem. In this paper, we analyze the signal-to-interference and noise ratio (SINR) distribution of downlink multi-user massive MIMO with MRT precoding in a movable railway & maritime adjacent multi-cell environment and derive a new mathematical formula for the outage probability. We also compare the derived results with simulation results to confirm their consistency.
