… the imperfect SIC and … imperfect SIC and CSI in the MH-DF-R-NOMA. We derive the
closed-form BER expression at each intermediate relay node for each user symbol with the imperfect …

… considers relaying NOMA as existence of hardware noise and interference of imperfect
SIC … We examine the system performance of the proposed system and develop a closed-form …

… However, in [9], the performance of a NOMA based CRS was studied, where two sources …
the help of an AF relay. In [10], a NOMA system with a relaying concept has been proposed, in …

… of the CR-NOMA-PS, when the relay operates in the DF protocol, has been investigated.
The practical scenarios are considered with imperfect SIC and CSI. Under imperfect CSI, we …

… to secure the transmission of the untrusted relay assisted NOMA networks. For the single
and … for the legitimate users to mitigate the effect of the SIC error caused by imperfect SIC. …

… systems in practice. Therefore, in this paper, a cooperative overlay CR-NOMA system in the
presence of imperfect SIC … In this network, cell-center cognitive SUs act as relays to assist …

… We have studied the OP and ergodic sum-rate behavior of the downlink NOMA with TAS/MRC
in the dual-hop AF relaying system over Nakagami-m fading channels with …

… To access more insights into the system performance of NOMA with AF relay, in this
section, Monte Carlo simulations are performed. The relationships between mobile users and …
