Energy efficient NOMA based beamforming and power control architecture for Future communication networks

Abstract

In the current and future wireless technologies beamforming techniques are one of the key features to fit in with the higher throughput demands of users for various data exhaustive applications. Simulation of energy efficient 5G network with enabled NOMA (non orthogonal multiple access) and beamforming capabilities has been done in this paper. A partially connected hybrid beamforming architecture for multiantenna NOMA based transmitter has been proposed. A test bed of fully connected phase shifters and adjustable attenuators and multiple antennas arrays with beamforming capabilities outperform the various other sub connected models. Moreover this kind of architecture makes use of hybrid beamforming to fulfill higher capacity and low power consumption requirements of network. Simulations results are presented to demonstrate the performance of proposed architecture. Hence NOMA based trans-receivers along with hybrid beamforming technique has the potential to significantly improve the performance of the network in terms of energy efficiency.
