Internet-of-Things (IoT) technology has received much attention due to its great potential to
interconnect billions of devices in a broad range of applications. IoT networks can provide …

Non-orthogonal multiple access (NOMA)-based cognitive radio (CR) networks have recently
emerged as a promising solution to enhance the spectral efficiency and massive …

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 article, we study novel wireless powered cognitive nonorthogonal multiple access
(NOMA)-based Internet-of-Things (IoT) relay networks to improve the performance of a cell …

Non-orthogonal multiple access (NOMA) system can meet the demands of ultra-high data
rate, ultra-low latency, ultra-high reliability and massive connectivity of user devices (UE) …

In this study, the performance of a secondary network in cognitive radio (CR) is studied in
the context of vehicle-to-everything (V2X). The non-orthogonal multiple access (NOMA) is …

In this paper, we investigate an underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission network with imperfect successive …

This study considers the outage and throughput performance of downlink in the secondary
network of cognitive radio assisted non-orthogonal multiple access (NOMA) systems. Both …

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 paper, we propose short-packet communications (SPCs) with non-orthogonal multiple
access (NOMA) for coordinated and direct relay transmission (CDRT) Internet-of-Things …
