In this paper, we study the outage probability (OP) of the cooperative underlay cognitive
radio (CR) networks consisted of a secondary relay node and K non-orthogonal multiple …

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 …

In this study, the performance of non-orthogonal multiple access systems (NOMA) in relay
assisted cognitive radio (CR) networks is investigated. Mathematical inferences in the …

This paper investigates outage and throughput performance of non-orthogonal multiple
access (NOMA) based underlay cognitive radio (ie, CR-NOMA) network under partial relay …

Non-orthogonal multiple access (NOMA) has been recently regarded as one of the potential
multiple access candidates for coming fifth generation (5G) communication networks. In this …

This paper investigates the impact of partial relay selection scheme (PRSS) on cooperative
underlay cognitive radio (CR) non-orthogonal multiple access (NOMA) networks. Decode …

Non-orthogonal multiple access (NOMA) is considered to be one of the promising multiple
access (MA) techniques for 5G networks that can provide low latency, high system …

In conventional cognitive radio (CR), the users in secondary network (SN) can only access
the idle spectrum when users in primary network (PN) are absent. This novel strategy …

In this paper, we analyze the performance of an underlay downlink non-orthogonal multiple
access (NOMA) network with multiple near and far-users. Different from cognitive radio (CR) …

In this paper, nonorthogonal multiple access (NOMA) is applied to large-scale underlay
cognitive radio (CR) networks with randomly deployed users. To characterize the …
