In this paper, nonorthogonal multiple access (NOMA) is applied to large-scale underlay
cognitive radio (CR) networks with randomly deployed users. To characterize the …

This correspondence paper considers a dual-hop underlay cognitive radio nonorthogonal
multiple access (NOMA) network. The end-to-end outage probability (OP) is evaluated as …

Nonorthogonal multiple access (NOMA) represents a paradigm shift from conventional
orthogonal multiple-access (MA) concepts and has been recognized as one of the key …

The synergy of nonorthogonal multiple access (NOMA) and cognitive radio (CR) can provide
efficient spectrum utilization for future wireless networks and enable supporting …

In this article, we investigate the performance of spectrum sharing inunderlay cognitive radio
(CR)-inspired nonorthogonal multiple access (NOMA) systems, at which a primary …

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 …

Recently, the increasing demand of radio spectrum for the next generation communication
systems due to the explosive growth of applications appetite for band-widths has led to 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 paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

In this paper, cognitive radio (CR) based on non-orthogonal multiple access (NOMA) is
considered over frequency non-selective Rayleigh fading channels. The two techniques are …
