This paper investigates the performance of an underlay cognitive hybrid satellite-terrestrial
network comprising a primary satellite source with its multiple terrestrial primary receivers …

In this paper, we analyze the performance of a non-orthogonal multiple access (NOMA)
cognitive relay system, where a multi-antenna full-duplex cognitive transmitter employs …

Two emerging technologies toward 5G wireless networks, namely non-orthogonal multiple
access (NOMA) and cognitive radio (CR), will provide more efficient utilization of wireless …

This paper investigates non-orthogonal multiple access (NOMA), cooperative relaying, and
energy harvesting to support device-to-device (D2D) transmission. In particular, we deploy …

The nonorthogonal multiple access (NOMA) well improves the spectrum efficiency which is
particularly essential in the Internet of Things (IoT) system involving massive number of …

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 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 …

This paper proposes a cooperative nonorthogonal multiple access (CNOMA) scheme in a
full-duplex (FD) relaying cognitive radio network (CRN), where a primary user (PU) …

This work studies a simultaneous wireless information and power transfer based downlink
non-orthogonal multiple access (NOMA) network. The near user is equipped with a non …

In this article, we propose a downlink non-orthogonal multiple access (NOMA) based
coordinated direct and relay system with one cell-center user and multiple cell-edge users …
