In this paper, we propose and evaluate performance of multihop multipath underlay
cognitive radio networks. In a primary network, an uplink nonorthogonal multiple access …

In this paper, we propose and evaluate outage performance of a mixed amplify-and-forward
(AF) and decode-and-forward (DF) relaying protocol in underlay cognitive radio. Different …

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 a multi-hop multiple input multiple output (MIMO) decode-and-
forward relaying protocol in cognitive radio networks. In this protocol, a multi-antenna …

This paper investigates the impact of primary transmissions on the performance of a dual-
hop bidirectional cognitive radio system. The secondary users (SUs) communicate with each …

In this paper, we present the optimal power allocation and relay precoder design for a
cognitive relay network employing non-orthogonal multiple access (NOMA) technique. The …

In this letter, we address the problem of maximizing the throughput of underlay cognitive
networks, through optimal power allocation of non-orthogonal amplify-and-forward relays …

In this paper, an adaptive two-way relay cooperation scheme is studied for multiple-relay
cognitive radio networks to improve the performance of secondary transmissions. The power …

In this paper, we evaluate end-to-end outage probability of a multi-hop decode-and-forward
relaying protocol in underlay cognitive radio network. In the proposed protocol, named …

In this paper, we study the application of the non orthogonal multiple access (NOMA) and
orthogonal multiple access (OMA) scheme to cooperative cognitive radio network. We …
