This paper studies a downlink security-aware secure outage performance in the secondary
network of cognitive radio-assisted non-orthogonal multiple access network (CR-NOMA) …

A two-user cooperative non-orthogonal multiple access (NOMA) network can be improved
by exploiting the relay selection (RS) scheme. The best relay selected from the relay can …

This paper presents the secrecy performance of Cognitive Radio (CR) networks by enabling
non-orthogonal multiple access (NOMA) in downlink. The multiple-input and single output …

As more and more users are using wireless devices, the demand for higher data rate has
increased. Therefore, new technologies are being developed to meet the needs. One such …

In this paper, we study uplink-downlink non-orthogonal multiple access (NOMA) systems by
considering the secure performance at the physical layer. In the considered system model …

This paper considers power domain based multiple access (PDMA) in cognitive radio
network to serve numerous users who intend to multiple access to core network. In …

Fading is considered to be one of the major issues in wireless communications. The non-
Orthogonal Multiple Access (NOMA) technique proved to be efficient enough to overcome …

In a wireless system, dual-hop transmission requires Full-Duplex (FD) to transmit signals
from the base station too far users. It is more beneficial if we deploy non-orthogonal multiple …

With the ever-increasing satellite and terrestrial communication demands in our 5G era,
integrating cooperative transmission into satellite networks is seen as a viable technique for …

In this paper, the outage performance of CR-NOMA schemes in decode-and-forward (DF)
relay systems Device-to-Device (D2D) with antenna selection is investigated. We propose …
