This paper studies a new amplify-and-forward cooperative overlay cognitive radio (CR) non-
orthogonal multiple access (AFCO-NOMA) system, where a primary network shares its …

This paper investigates the performance analysis of cognitive-inspired wireless-powered
non-orthogonal multiple access (NOMA) systems, where two collaborative schemes are …

This study outlines a non‐orthogonal multiple access (NOMA) scheme for cooperative
multicasting in a cognitive radio network. The network consists of a common base station …

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 a multiuser underlay uplink network, we show that despite the fact that the transmit powers
are constrained by the interference temperature limit (ITL) imposed by the primary network …

Non-orthogonal multiple access (NOMA) is emerging as a promising, yet challenging,
multiple access technology to improve spectrum utilization for the fifth generation (5G) …

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) …

In this paper, we investigate an underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission network with imperfect successive …

Semi-grant-free (SGF) transmission has recently received significant attention due to its
capability to accommodate massive connectivity and reduce access delay by admitting grant …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient multiple access
technique for the fifth generation (5G) wireless networks. In this paper, we propose a …
