This paper presents non-orthogonal multiple access (NOMA)-based spectrum sharing
scheme for cooperative underlay cognitive radio (CR) wherein the cell-edge primary …

This paper proposes a novel non-orthogonal multiple access (NOMA)-based cooperative
transmission scheme for a spectrum-sharing cognitive radio network (CRN), whereby a …

In non‐orthogonal multiple access (NOMA) systems, it may not be advisable to send the
superimposed signal of all users to individual users with retransmission requirements during …

In the existing underlay cognitive radio literature, the outage performance of the secondary
network is severely degraded due to the interference from the primary network and the …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

This paper investigates the opportunistic sharing of relay for the proposed Non-Orthogonal
Multiple Access (NOMA) assisted Cognitive Radio Networks (CRNs). The proposed scheme …

In this paper, we study the application of the non orthogonal multiple access (NOMA) and
orthogonal multiple access (OMA) scheme to cooperative cognitive radio network. We …

This paper proposes a cooperative uplink–downlink non orthogonal multiple access
(NOMA) in an overlay cognitive radio network (CR). We examine the impact of imperfect …

In this paper, we study a power domain non-orthogonal multiple access (NOMA) scheme for
cognitive cooperative radio networks (CCRNs). In the proposed scheme, a secondary …
