Uplink sum-throughput evaluation of sectorized multi-cell massive MIMO system
In this paper, a sectorized multi-cell massive multiple-input multiple-output (MIMO) system is considered with a spatially correlated channel model. Since sum-throughput per cell is an important index for evaluating a multi-cell system, we derive the ergodic achievable uplink sum-throughput per cell of the sectorized system and give the deterministic approximation of it based on the large random matrix theory. Numerical results indicate that sum-throughput per cell can be greatly increased compared to the conventional multi-cell massive MIMO system, which validates the effectiveness of the sectorized system. Moreover, it can be seen that the deterministic approximation is consistent with the result of Monte-Carlo simulation.
