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 …

In this study, a cooperative non‐orthogonal multiple access (NOMA) scheme is investigated
in an underlay cognitive radio network. With this aim, a number of secondary users are …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

Combining energy harvesting with cognitive radio and nonorthogonal multiple access
(NOMA) techniques will be a notable candidate for improving both energy and spectral …

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 …

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 paper, we analyze the performance of an energy harvesting (EH)-assisted overlay
cognitive non-orthogonal multiple access (NOMA) system. The underlying system consists of …

In this letter, we investigate the performance of an overlay cognitive satellite-terrestrial
network comprising a primary satellite source with its multiple terrestrial receivers and a …

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 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 …
