Abstract
In this paper, an energy-efficient resource allocation alogrithm for massive multiple-input-multiple-output (MIMO) systems powered by wireless power transfer (WPT) with hardware impairments at sensor nodes (SNs) is investigated. In the considered system, the sensor nodes are powered by the WPT from power beacon (PB), then the SNs use the harvested energy to transmit data to the base station (BS) with large-scale multiple antennas. An energy efficient resource allocation algorithm that combines time and power allocation is proposed to maximize the energy efficiency of the systems. Simulation results have been given to show the effectiveness of the proposed algorithm compared with the throughput maximization algorithm.
