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 …

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

As a promising technique, power beacon provides ability of wireless energy transfer to
relaying devices in Internet of Things (IoT) to serve far devices with respect to low latency …

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 …

In this paper, an Internet-of-Things (IoT) system containing a relay selection is studied as
employing an emerging multiple access scheme, namely non-orthogonal multiple access …

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 study the joint impact of residual hardware impairments (RHIs) and
imperfect channel state information (ICSI) on cooperative non-orthogonal multiple access …

In normal non-orthogonal multiple access (NOMA) network, perfect successive interference
cancellation (SIC) and perfect hardware impairments are usually admitted at transceivers …

In this paper, a hybrid satellite-terrestrial spectrum sharing system allows terrestrial
secondary network to cooperate with a primary satellite network and to further provide …

In this paper, we investigate power domain division-based multiple access (PDMA) to
support the base stations (BS) equipped with multiple antennas to serve mobile users. Such …
