Secure nonorthogonal multiple access with energy harvesting-assisted full-duplex receivers

This paper investigates securing nonorthogonal multiple access (NOMA) by leveraging receivers equipped with full-duplex (FD) communication and energy harvesting (EH) capabilities. These receivers decode their intended information while simultaneously jamming eavesdroppers using harvested energy, aiming to achieve high security, energy efficiency, and spectral efficiency. The study analyzes the proposed NOMA scheme with EH-assisted FD receivers across various key performance metrics for a quick performance assessment. The proposed analysis is validated through simulations, which demonstrate the influence of the proposed model on multiple specifications. Furthermore, the proposed model is shown to be considerably more secure than the conventional orthogonal multiple access (OMA) with EH-assisted FD receivers, revealing the advantages of NOMA over OMA.
