An iterative Power Allocation Alogrithm for Energy Efficiency Optimization in Massive MIMO Systems
Journal Title: EAI Endorsed Transactions on Internet of Things - Year 2017, Vol 3, Issue 10
Abstract
In this paper, a transmitting power allocation strategy for users jointed together pre-coding is presented to eliminate inter-users interference and improve the energy efficiency of Massive MIMO systems. The power allocation model is formularized as energy efficiency optimization problem of the users ’ power and circuit power consumption. We demonstrate that energy efficiency is a convex function of users’ power. In order to reduce the complexity of traditional power allocation algorithm, an iterative power allocation algorithm based on convex optimization theory is proposed to figure out the optimal value of each user power. The simulation results show that the iterative algorithm can effectively improve the energy efficiency of Massive MIMO systems.
