Performance Analysis of Uplink NOMA-Assisted Full-Duplex Amplify-and-Forward CR Network

Abstract

In this article, we propose and analyze a new non-orthogonal multiple access (NOMA) assisted full-duplex amplify-and-forward cooperative relaying (NOMA-assisted FACR) network. The uplink NOMA principle is used to forward message symbols by employing an amplify-and-forward relay working in full-duplex mode over Rayleigh fading channels. An approximate closed-form expression is derived for the outage probability of the presented model. The outage performance of the NOMA-assisted FACR is compared with the recently presented models. Moreover, the article also studies the impact of power allocation coefficients and detection threshold on outage performance. Simulations are carried out to verify the evaluated analytical results.
