On the Outage Performance of Uplink NOMA Inspired CR Network with CEEs and Imperfect SIC

In this article, a novel non-orthogonal multiple access (NOMA) inspired decode-and-forward cooperative relay (CR) network working in full-duplex mode is presented. The NOMA principle in uplink model is used to transmit symbols from the user to base station (BS) by employing a relay over Rayleigh fading channel. Outage probability (OP) expression is evaluated at the BS under channel estimation error (CEE) and imperfect successive interference cancellation (SIC) conditions. The article compares the presented model with the recently presented systems. We also investigate the impact of power allocation coefficient and CEEs on the OP of the presented scheme. Simulations are carried out to validate the analytical expressions.
