This work aims to investigate an asymmetrical NOMA transmission network based on
cognitive radio, where both the source and relay nodes of the secondary user are energy …

This paper considers the application of non-orthogonal multiple access (NOMA) into
cooperative cognitive radio (CR) networks with simultaneous wireless information and …

Both cognitive radio and non-orthogonal multiple access (NOMA) are spectral efficient
techniques in the future wireless communication networks. In this paper, a novel cooperative …

This paper jointly studies cognitive radio (CR) and non-orthogonal multiple access (NOMA)
networks by adopting an energy restricted amplify-and-forward relay. We study the outage …

In this paper, we examine non-orthogonal multiple access (NOMA) and relay selection
strategy to benefit extra advantage from traditional cognitive radio (CR) relaying systems …

In this paper, a cooperative non-orthogonal multiple access (NOMA) network is considered,
where a source communicates with two users through an energy harvesting relay. The …

This paper investigates a multiple users cooperative cognitive non‐orthogonal multiple
access (NOMA) network with energy harvesting. Primary transmitter and secondary sources …

Improving spectral efficiency under a certain energy limitation is an important design metric
for future wireless communications as a response to the growing transmission demand of …

In this paper, we investigate a relay-assisted cooperative spectrum sharing for the
considered non-orthogonal multiple access (NOMA) scheme in cognitive radio networks …

The cooperative non-orthogonal multiple access (NOMA) networks with one pair primary
user and one pair cognitive user share the same spectrum resource via a common relay is …
