In this paper, we investigate the effectiveness of an overlay cognitive radio (OCR) coupled
with non-orthogonal multiple access (NOMA) system using a full-duplex (FD) cooperative …

In cognitive radio networks (CRNs), the performance of the primary users (PUs) may suffer
adverse effects from the secondary users (SUs) if the spectrum of PUs is haphazardly …

The joint uplink/downlink (JUD) design of simultaneously transmitting and reflecting
reconfigurable intelligent surfaces (STAR-RIS) is conceived in support of both uplink (UL) …

In this work, a novel time and relay shared (TRS) based full/half duplex (FD/HD) cooperative
non-orthogonal multiple access (C-NOMA) scheme namely TRS FD/HD C-NOMA is …

This paper presents a non-orthogonal multiple access (NOMA)-based spectrum sharing
scheme with imperfect successive interference cancellation (i-SIC), where the secondary …

In this paper, we analyze the performance of a full-duplex (FD) cooperative non-orthogonal
multiple access (C-NOMA) relaying system with an amplify-and-forward (AF) protocol in the …

To solve the problems of complex energy supply and poor communication effect of cell-edge
users, combining the advantages of simultaneous wireless information and power transfer …

The fifth generation (5G) and beyond-5G networks aim to meet the rapidly growing traffic
demands while considering the scarcity of radio resources and the heterogeneity of services …

Cooperative spectrum sharing is a method to allocate the radio spectrum amongst users for
high-velocity wireless networks. It entails multiple unbiased customers that cooperate to …

To meet the escalating demand for bandwidth and data rates, this paper introduces a
cooperative model to enhance the quality of service (QoS) for users at the edge of a cell …
