This letter investigates an energy harvesting (EH)-assisted coordinated direct and relay
transmission in an overlay cognitive non-orthogonal multiple access (NOMA) system …

This paper studies the application of simultaneous wireless information and power transfer
(SWIPT) to downlink non-orthogonal multiple access (NOMA) system. A novel cooperative …

In this letter, we investigate the optimal power allocation scheme in a cooperative relaying
system using non-orthogonal multiple access from the perspective of global energy …

For a downlink communication system, we propose a nonorthogonal multiple access
scheme with two energy harvesting relays. The base station (BS) transmits the data of both …

In this paper, the power allocation of Non-orthogonal multiple access (NOMA) for secondary
users in underlay cognitive radio is studied. In underlay cognitive radio networks, the …

The cooperative non-orthogonal multiple access (NOMA) networks with one pair primary
user and one pair cognitive user share the same spectrum resource via a common relay is …

This paper focuses on the problem of sensing throughput optimization in a fading multiple
access cognitive radio (CR) network, where the secondary user (SU) transmitters participate …

This letter focuses on cooperative resource allocation in multi-carrier cognitive radio (CR)
networks where the primary user (PU) is wirelessly powered by the energy harvested from …

This paper investigates the energy-efficient transmission under hybrid spectrum sharing
scenario, where secondary users (SUs) can select a proper spectrum sharing method based …

In this aticle, an optimal policy is presented to maximize the secondary user's (SU's)
throughput in an energy harvesting cognitive radio network with multiple SUs and single …
