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

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 a non-orthogonal multiple access (NOMA) assisted cognitive
satellite-terrestrial network which is practically limited by interference noises, transceiver …

In this paper, we employ power-domain non-orthogonal multiple access (NOMA) to
simultaneously transmit signals to both a primary user (PU) and a secondary user (SU) of a …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

Software defined radio (SDR) networks are required to achieve endurance, reliability,
efficient data transmission, and adaptability to various operating requirements. Their …

Cognitive radio-based non-orthogonal multiple access (CR-NOMA) is considered to be one
of the promising multiple accessing technique candidates for 5G and beyond networks …

This paper investigates the outage performance of secondary users (SUs) in underlay
cognitive radio–based nonorthogonal multiple access (CR‐NOMA) networks. We consider …

The rapid growth in the use of mobile devices and wireless services has led to a shortage of
available spectrum for communication. To solve this issue, Cognitive Radio (CR) has been …

To alleviate the strict synchronization requirements and avoid the high peak-to-average
power issue, asynchronous cyclic prefixed single carrier (CP-SC) transmission is applied for …
