A Survey on Using Full Duplex Technology in Energy Harvesting Systems

The ever-increasing advances in technology have raised wireless systems as one of the inseparable parts of everyday life. Following these advances, the demand for spectrum resources increases every day in order to support more users in a wireless network. Due to the ever-increasing need for bandwidth and efficient utilization of the capacity of telecommunication wireless networks, Full Duplex (FD) technology has recently drawn the attention of researchers. By sending and receiving information simultaneously in the same frequency band, this technology can improve the spectral efficiency up to twice in comparison with traditional Half Duplex (HD) systems. In addition, energy harvesting systems have emerged in recent years as a solution to the problem of power consumption of nodes in wireless networks. In this paper, first, different scenarios of using FD communication technology in energy harvesting systems are discussed and compared. Then, the objective functions used in the design of these systems are examined. Finally, the challenges of using FD communication technology in energy harvesting systems are discussed.
