Area Coverage of a Multi-Link MIMO System With Water Filling Power Allocation Strategy

In this paper, the authors propose a power allocation of multi-link MIMO system. The multi-link MIMO system transmits different signals to a mobile station by using plural base stations with multiple antennas. The system improves not only area coverage but also spectrum efficiency. Here water filling power allocation strategy is used to optimize the capacity of the multi-link MIMO channel. This paper focuses on the downlink channel and presents single-user performance of the system. The performance is evaluated by area coverage that is, the percentage of the locations where the capacity exceeds the target value.
