Outage Performance of Antenna Selection Schemes in NOMA Networks using Amplify-and-Forward Energy Harvesting Relay

Abstract

In this work, outage performance of joint transmitreceive antenna selection and receive antenna selection techniques in non-orthogonal multiple access network using half-duplex amplify-and-forward energy harvested relay is examined over Rayleigh fading channels. In the system, one base station with multiple antennas communicates with two users with multiple antennas simultantaneously via an energy harvesting relay. Energy harvesting half-duplex amplify-and-forward relay is equipped with multiple receive antennas and single transmit antenna. The outage probabilities related to the users, which is expressed with the help of the end-to-end signal-to-interference plus noise ratio, is investigated through Monte Carlo simulations.
