In this paper, we consider non-orthogonal multiple access (NOMA) relaying networks, where
one base station communicates with two mobile users with the aid of multiple relays. We …

Non-orthogonal multiple access (NOMA)-based cognitive radio (CR) networks have recently
emerged as a promising solution to enhance the spectral efficiency and massive …

In this correspondence, the outage probability (OP) of dual-hop cognitive amplify-and-
forward (AF) relay networks subject to independent non-identically distributed (inid) …

This paper investigates the use of full duplex relaying (FDR) in cognitive radio systems.
Cognitive full duplex relay networks (CogFRNs) offer the advantage not only of increasing …

We examine the impact of multiple primary transmitters and receivers (PU-TxRx) on the
outage performance of cognitive decode-and-forward relay networks. In such a joint …

This paper proposes and analyzes cognitive multihop decode-and-forward networks in the
presence of interference due to channel estimation errors. To reduce interference on the …

In this paper, the outage behavior of dual-hop multiuser multirelay cognitive radio networks
under spectrum-sharing constraints is investigated. In the proposed cognitive radio network …

Internet-of-Things (IoT) technology has received much attention due to its great potential to
interconnect billions of devices in a broad range of applications. IoT networks can provide …

In the presence of the primary user's interference, the outage probability of a dual-hop
decode-and-forward (DF) cognitive relay network (CRN) over Rayleigh fading channels is …

In this work, we investigate short-packet communications for multiple-input multiple-output
underlay cognitive multihop relay networks with multiple primary users, where transceivers …
