… connected to two different relays in the proposed … NOMA-based TWR scheme with two
popular relaying modes, namely, amplify-and-forward (AF) and decode-and-forward (DF) relaying, …

… a new scheme to secure the transmissions in the NOMA network. We examine secure
outage performance of such NOMA networks under coexistence of relay link and direct links. …

… of relay selection on the performance of cooperative NOMA, and we focus on two types of
relay … Assume that there is no direct link between the BS and the users, and the BS-relay and …

… NOMA scenario where a CCU directly communicates with a BS, whereas a CEU needs the
help of a DF relay … quality by treating the user symbol (ie y1) subject to the inferior link quality …

… 4) With direct link: We analyze the ergodic rate of far user for FD/HD NOMA. For this scenario,
it is the fact that the ergodic rate of near user is invariant which is not affected by the direct …

… To examine the impact of the relay location variations on the coding gain of the proposed …
NOMA scheme including the direct and indirect links is studied in [24], where a dedicated relay …

… destinations via a common relay. For cognitive relay NOMA networks, we propose a novel
… We use the DF relaying scheme to establish two-hops communication links. All nodes in Fig…

… Utilizing CRS, the authors of [21] studied the performance of a downlink NOMA-based
CRS over Nakagami-m fading channels. By comparing the performance between decode-and-…

… capacity, relay or RIS? Hence, in this letter, we answer it by developing and analyzing novel
RIS- or relaying-assisted cooperative networks with NOMA, where the direct link from the …

… RS scheme for cooperative NOMA considering both users’ … suitable for more scenarios (eg
cognitive NOMA). Specifically, the … dual-hop DF relaying in the presence of a direct link,” IEEE …
