Energy Efficient Water-Filling Power Allocation with Cell Division for Massive MIMO Systems
Abdolrasoul Sakhaei Gharagezlou, Jafar Pourrostam, Mahdi Nangir +1
In this paper, we consider the power allocation problem for the downlink of the massive multiple-input multiple-output (MIMO) systems. We propose a new scheme by exploiting the wat…
