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 …

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 …

Non-orthogonal multiple access (NOMA) is one of the most effective techniques for meeting
the spectrum efficiency (SE) requirements of 5G and beyond networks. This paper presents …

In this paper, we consider the secrecy of a hybrid radio frequency (RF)/visible light
communication (VLC) system equipped with decode-and-forward relaying. We develop …

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 decode-and-forward wireless powered relaying cognitive radio
network with interference alignment over Rayleigh fading channels is investigated. The …

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 …

Wireless power transfer and energy harvesting have attracted a significant research
attention in terms of their application in cooperative relaying systems. Most of existing works …

In this paper, we study physical layer security (PLS) aspects of a hybrid radio frequency
(RF)/visible light communication (VLC) system with multiple decode-and-forward relaying …

In this paper, we consider a two-hop amplify-and-forward (AF) relaying system, where the
relay node is energy-constrained and harvests energy from the source node. In the …
