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 …

This paper proposes a cooperative uplink–downlink non orthogonal multiple access
(NOMA) in an overlay cognitive radio network (CR). We examine the impact of imperfect …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

In non‐orthogonal multiple access (NOMA) systems, it may not be advisable to send the
superimposed signal of all users to individual users with retransmission requirements during …

In this study, a cooperative non‐orthogonal multiple access (NOMA) scheme is investigated
in an underlay cognitive radio network. With this aim, a number of secondary users are …

This paper investigates outage and throughput performance of non-orthogonal multiple
access (NOMA) based underlay cognitive radio (ie, CR-NOMA) network under partial relay …

This paper is considered as an application of a centralized control non orthogonal multiple
access (NOMA) based cognitive radio network. Here, a base station (BS) sends …

In this letter, a cooperative non-orthogonal multiple access system with imperfect successive
interference cancellation is investigated in an underlay cognitive radio network. Considering …

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 letter, a cooperative underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission is investigated. Specifically, exact closed …
