Background: Non-orthogonal multiple access (NOMA) is a promising technique for
improving wireless communication performance in the future. In addition to NOMA, cognitive …

In this paper, we investigate the outage performance in secondary network of cognitive radio
(CR) employing non-orthogonal multiple access (NOMA) wireless networks over Rayleigh …

In this paper, we investigate the performance of a secondary network in a cognitive radio
network employing a non-orthogonal multiple access (NOMA) scheme to form a CR-NOMA …

In this paper, we investigate improved spectrum concern by employing non-orthogonal
multiple access (NOMA) scheme in cognitive radio (CR) network to form CR-NOMA and to …

Future 5G technologies increase spectrum efficiency and wireless capacity by supporting
numerous connections at once. New designs are therefore required in order to support the …

In this work, we propose and investigate a novel hybrid cellular and bidirectional device-to-
device (D2D) transmission scheme that exploits cooperative non-orthogonal multiple access …

In traditional cognitive radio (CR), secondary user (SU) can only access the idle spectrum
when primary user (PU) is absent, which has to vacate the spectrum when detecting the …

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

We propose and investigate a bidirectional device-to-device (D2D) transmission scheme
that exploits cooperative downlink non-orthogonal multiple access (NOMA)(termed as BCD …

With the dramatic development of wireless communication technology, intelligent
transportation systems (ITS) are facing the problems of low spectrum utilization and …
