Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are promising for solving
the severe spectral scarcity problem encountered by the next generation of wireless …

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

We present a downlink secondary network over Rician fading model since cognitive radio
(CR) based non-orthogonal multiple access (NOMA) is adopted. Due to interference …

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 …

Both non-orthogonal multiple access (NOMA), which can serve multiple users
simultaneously and on the same frequency, and cognitive radio (CR) can contribute to …

In this article, the performance of cognitive radio system benefits from non-orthogonal
multiple access (NOMA) scheme. We then examine system metrics to adjust its quality of …

Cognitive radio-based non-orthogonal multiple access (CR-NOMA) is considered to be one
of the promising multiple accessing technique candidates for 5G and beyond networks …

In this paper, we investigate the resource allocation in an underlay cognitive radio network
when multiple primary and secondary users are served via multi-carrier non-orthogonal …

The primary objective of cognitive radio network is to effectively utilize the unused spectrum
bands. In cognitive radio networks, spectrum sharing between primary and secondary users …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …
