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 …

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 …

The non‐orthogonal multiple access (NOMA) technique offers throughput improvement to
meet the demands of the future generation of wireless communication networks. The …

In this paper, we derive the throughput of non-orthogonal multiple access NOMA with
adaptive transmit power for cognitive radio networks (CRN). The secondary source and …

Spectrum resources are the precious and limited natural resources. In order to improve the
utilization of spectrum resources and maximize the network throughput, this paper studies …

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 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 …

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

The explosive growth of mobile devices, as well as the increasing demand for wireless
services, has created a situation of serious spectrum shortage. A solution to this problem is …
