In this paper, we consider an energy efficient resource allocation technique for a hybrid time
division multiple access (TDMA)-non-orthogonal multiple access (NOMA) system. In such a …

We integrate a wireless powered communication network with a cooperative cognitive radio
network, where multiple secondary users (SUs) powered wirelessly by a hybrid access point …

We investigate the energy efficiency (EE) in cognitive radio networks, where cognitive users
are allowed to access a licensed frequency band opportunistically, provided that the …

Non-orthogonal multiple access (NOMA)-based cognitive wireless networks can improve the
spectral efficiency to utilize the vacant spectrum resource and exploit the power domain …

In this paper, we propose and analyze a downlink non-orthogonal multiple access (NOMA)
relay system with full-duplex transmission model and decode-and-forward (DF) scheme. We …

Simultaneous wireless information and power transfer (SWIPT) that can prolong the lifetime
of energy-limited wireless users has drawn considerable attention. In this paper, the power …

Non-orthogonal multiple access (NOMA) is considered as one of the promising techniques
for providing high data rates in the fifth generation mobile communication. By applying …

In this letter, we study a receiver architecture technique for joint resource allocation in a
downlink (DL) multi-user multi-carrier non-orthogonal multiple access (MC-NOMA) network …

Cognitive radio (CR) has been proposed as a strategy to enhance the spectrum utilization
efficiency. In a CR network, the secondary users (SUs) share the same radio spectrum with …

In this paper, we analyze the performance of a novel communication scheme that combines
three new techniques, namely energy harvesting (EH), full-duplex (FD) relay and …
