The performance of an underlay coordinated direct and relay transmission (CDRT) based
non-orthogonal multiple access (NOMA) network is limited by the random nature of the …

In this article, we investigate the performance of spectrum sharing inunderlay cognitive radio
(CR)-inspired nonorthogonal multiple access (NOMA) systems, at which a primary …

In this paper, we investigate a multiple users cooperative overlay cognitive radio non-
orthogonal multiple access (CR-NOMA) network in the presence of imperfect successive …

This paper investigates reconfigurable intelligent surface (RIS)-aided cognitive non-
orthogonal multiple access (NOMA) systems, where an RIS is deployed to serve two users …

In this letter, a cooperative underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission is investigated. Specifically, exact closed …

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 …

The continued growth of the industrial Internet of Things (IoT) paves the way for the fifth
industrial revolution (Industry 5.0), which is expected to further enhance the wireless …

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 investigate the effects of residual hardware impairments (RHIs), channels
estimation errors (CEEs) and imperfect successive interference cancellation (ipSIC) on the …

Satellite-terrestrial networks (STNs) have received significant attention from research and
industry due to their capability of providing a stable connection to rural and distant areas …
