In this paper, we demonstrate that despite the power constraints on all transmit nodes
caused by the interference temperature limit (ITL) imposed by the primary user, power …

Non-orthogonal multiple access (NOMA) has been recently regarded as one of the potential
multiple access candidates for coming fifth generation (5G) communication networks. In this …

The continued growth of the industrial Internet of Things (IoT) paves the way for the fifth
industrial revolution (Industry 5.0), which is expected to further enhance the wireless …

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 conventional cognitive radio (CR), the users in secondary network (SN) can only access
the idle spectrum when users in primary network (PN) are absent. This novel strategy …

In this paper, we propose and evaluate performance of multihop multipath underlay
cognitive radio networks. In a primary network, an uplink nonorthogonal multiple access …

In this paper, the power allocation of Non-orthogonal multiple access (NOMA) for secondary
users in underlay cognitive radio is studied. In underlay cognitive radio networks, the …

This paper considers the application of non-orthogonal multiple access (NOMA) into
cooperative cognitive radio (CR) networks with simultaneous wireless information and …

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 a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …
