In this paper, nonorthogonal multiple access (NOMA) is applied to large-scale underlay
cognitive radio (CR) networks with randomly deployed users. To characterize 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 studies a new decode-and-forward cooperative overlay cognitive radio non-
orthogonal multiple access (DFCO-NOMA) system, where a secondary network shares the …

Non orthogonal multiple access (NOMA) in cognitive radio (CR) network has been
recognized as potential solution to support the simultaneous transmission of both primary …

In this paper, we consider a non-orthogonal multiple access (NOMA) based underlay
cognitive radio (CR) system consisting of a source, two destinations, and a relay in the …

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 …

In this paper, a random cognitive radio networks schemes combined with Non-orthogonal
Multiple Access (NOMA) is investigated. In the proposed protocol, relying on the channel …

In this letter, we propose a novel dynamic power allocation scheme for hybrid non-
orthogonal multiple access (DH-NOMA). The exact expressions for the outage probabilities …

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

Non-Orthogonal Multiple Access (NOMA) is a prospective paradigm, which drastically
improves spectral efficiency by permitting several users to partake concurrently the same …
