We consider a cognitive radio system, in which a secondary transmitter harvests energy from
a primary transmitter's RF signal. The secondary transmitter, which provides decode-and …

In this study, an energy harvesting (EH)‐based cooperative non‐orthogonal multiple access
(NOMA) system is considered, where node S simultaneously sends independent signals to …

This paper studies a multiple-input single-output non-orthogonal multiple access cognitive
radio network relying on simultaneous wireless information and power transfer. A realistic …

Energy Efficiency (EE) is a significant problem for Cognitive Radio (CR) network. Recently,
more interest has focused on EE optimization problem in wireless-powered communication …

Cognitive radio and non-orthogonal multiple access are promising for alleviating the severe
spectral scarcity problem encountered by the next generation wireless communication …

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 …

Non-orthogonal multiple access (NOMA) is a candidate multiple access scheme in 5G
systems to simultaneously accommodate tremendous number of wireless nodes. On the …

Recently, wireless powered cooperative cognitive radio networks (CRNs), which combine
the technologies of radio frequency (RF) energy harvesting and CR, have drawn great …

To compensate for the transmission efficiency in a cooperative non-orthogonal multiple
access (NOMA) system, we enable in-band full-duplex (IBFD) and two-way cognitive …

In this paper, we investigate a relay-assisted cooperative spectrum sharing for the
considered non-orthogonal multiple access (NOMA) scheme in cognitive radio networks …
