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

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 this paper, we propose a two-way relaying scheme using digital network coding in an
underlay cognitive radio network. In the proposed scheme, the transmit antenna selection …

Sixth generation (6G) networks must guarantee radio-resource availability for coexisting
users and machines. Here, non-orthogonal multiple access (NOMA) can address resource …

Wireless communication systems to date primarily rely on the orthogonality of resources to
facilitate the design and implementation, from user access to data transmission. Emerging …

In this letter, we study the power allocation problem of cooperative non-orthogonal multiple
access (C-NOMA) systems with coordinated direct and relay transmission (CDRT) in the …

Overlay networks allow the unlicensed transmitter (UT) to aid the licensed transmitter (LT) by
sending the superimposed signal including messages of both UT and LT with a higher …

The paper presents performance analysis of a multiuser Cooperative Non-Orthogonal
Multiple Access (CNOMA) network that is underlay to a primary network. A selected …

In overlay networks, the cognitive sender (CS) assists the primary transmitter (PT) by
broadcasting the superposed signal composed of both cognitive and primary information …

This article studies short-packet communication (SPC) in multireconfigurable intelligent
surface (RIS)-assisted multiantenna wireless systems. In this system, a sensor node …
