In this paper, we consider a non-orthogonal multiple access cognitive radio network, where
a full-duplex multi-antenna relay assists transmission from a base station (BS) to a cognitive …

For future wireless communication networks to be highly efficient with both spectrum and
energy, reconfigurable intelligent surface (RIS) has emerged as a practical technology. In …

To compensate for the transmission efficiency in a cooperative non-orthogonal multiple
access (NOMA) system, we enable in-band full-duplex (IBFD) and two-way cognitive …

Due to the shortage of spectrum resources, a nonorthogonal multiple access‐(NOMA‐)
based overlay cognitive integrated satellite‐terrestrial relay network is established in this …

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) is emerging as a promising, yet challenging,
multiple access technology to improve spectrum utilization for the fifth generation (5G) …

In this paper, we investigate a multiple users cooperative overlay cognitive radio non-
orthogonal multiple access (CR-NOMA) network in the presence of imperfect successive …

In this paper, we investigate the performance of non-orthogonal multiple access (NOMA)-
based overlay cognitive integrated satellite-terrestrial relay network with secondary network …

This letter investigates an energy harvesting (EH)-assisted coordinated direct and relay
transmission in an overlay cognitive non-orthogonal multiple access (NOMA) system …

This paper considers cognitive radio (CR) inspired non-orthogonal multiple-access (NOMA).
Such NOMA users with performance improvement can be achieved as deploying relay …
