we propose an overlay cooperative cognitive radio (CR) non-orthogonal multiple access
(NOMA) network which has channel estimation errors and imperfect successive interference …

This paper analyze a new cooperative hybrid underlay–overlay cognitive radio non-
orthogonal multiple access (CHCR-NOMA) system, where a secondary source and a …

In this paper, we propose an overlay cognitive radio (CR) non-orthogonal multiple access
(NOMA) network to improve the performance of the primary receiver (PR) as well as the …

In the existing underlay cognitive radio literature, the outage performance of the secondary
network is severely degraded due to the interference from the primary network and the …

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 …

This paper studies a new decode-and-forward cooperative overlay cognitive radio non-
orthogonal multiple access (DFCO-NOMA) system, where a secondary network shares the …

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 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 studies a new amplify-and-forward cooperative overlay cognitive radio (CR) non-
orthogonal multiple access (AFCO-NOMA) system, where a primary network shares its …

In this paper, we study a cooperative non-orthogonal multiple access (NOMA) system
underlying cognitive networks which adapt user relaying and selection combining. The …
