With the increase in the number of communication devices, the requirement for higher
bandwidth is essential. To achieve this goal, research and industrial communities have both …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

In this paper, we study radio frequency (RF)-powered underlay cognitive radio networks
(CRNs) with power-domain non-orthogonal multiple access (NOMA). In these networks, by …

Non-orthogonal multiple access (NOMA) is considered to be one of the promising multiple
access (MA) techniques for 5G networks that can provide low latency, high system …

In this paper, we study the outage probability (OP) of the cooperative underlay cognitive
radio (CR) networks consisted of a secondary relay node and K non-orthogonal multiple …

In this paper, a two-hop amplify-and-forward relaying system, where an energy-constrained
relay node entirely depends on the energy scavenged from the source signal, is …

Modern transportation infrastructures are considered as one of the main sources of the
greenhouse gases emitted into the atmosphere. This situation requires the decision-making …

This paper investigates the performance of iterative interference alignment (IA) with spatial
hole sensing in K-user multi-input multi-output (MIMO) cognitive radio (CR) networks. In the …

Distributions of colluding decode-and-forward (DF) opportunistic relays (ORs) employing
maximal ratio combining under outdated channel state information (CSI) and independent …

In this paper, a cooperative multi-hop vehicle-to-vehicle communication over free-space
optics (FSO) medium is examined, where unmanned aerial vehicles act as relay nodes …
