In Cognitive Radio Non-Orthogonal Multiple Access (CR-NOMA), hybrid successive
interference cancellation (SIC) was proposed to improve the probability for a secondary user …

The conflation of cognitive radio (CR) and non-orthogonal multiple access (NOMA) concepts
is a promising approach to fulfill the massive connectivity goals of future networks given the …

In uplink non-orthogonal multiple access (NOMA) channels, the existing cooperative
successive interference cancellation (SIC) and power control (PC) schemes lack the …

In this paper, we consider the power allocation (PA) problem in cognitive radio networks
(CRNs) employing nonorthogonal multiple access (NOMA) technique. Specifically, we aim …

This study considers the outage and throughput performance of downlink in the secondary
network of cognitive radio assisted non-orthogonal multiple access (NOMA) systems. Both …

In this paper, the power allocation (PA) problem is investigated in cognitive radio networks
(CRNs), employing non-orthogonal multiple access (NOMA) technique. In such a framework …

In ad hoc cognitive radio (CR) networks, medium access control (MAC) design has been
raised as a major challenge due to its highly dynamic nature and strong user diversity …

The integration between orthogonal frequency division multiple access (OFDMA), non-
orthogonal multiple access (NOMA), and cognitive radio (CR) technology has been recently …

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 …

This paper investigates the problem of spectrally efficient operation of a multiuser uplink
cognitive radio system in the presence of a single primary link. The secondary system …
