In this paper, we demonstrate that due to large variations in link signal-to-noise-ratios, the
key to good performance in underlay cooperative non-orthogonal multiple access (CNOMA) …

The paper presents performance analysis of a multiuser Cooperative Non-Orthogonal
Multiple Access (CNOMA) network that is underlay to a primary network. A selected …

The objective of this paper is to propose techniques for enhancing the physical layer security
(PLS) performance of half-duplex cooperative non-orthogonal multiple access (HD-CNOMA) …

This article considers non‐orthogonal multiple access (NOMA) enabled full‐duplex (FD)
underlay cognitive relay networks (ie, NOMA‐FDCRNs) with partial relay selection scheme …

This article studies the physical layer security in a downlink full-duplex cognitive non-
orthogonal multiple access sensor networks (FD-C-NOMA). Compared with the existing …

In this paper, we consider a non-orthogonal multiple access (NOMA) based underlay
cognitive radio (CR) system consisting of a source, two destinations, and a relay in the …

In this paper, we investigate the performance of hybrid cooperative non-orthogonal multiple
access (CNOMA) underlaid in a primary network. The CNOMA setup consists of a secondary …

In this study, the authors proposed the optimal beamforming (BF) design for multiuser
broadcast secure transmission under secrecy outage probability constraint with artificial …
