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 …

Non-orthogonal multiple access (NOMA) is a key to multiple access techniques for the next
generation 5G wireless communication networks. In this paper, to improve the performance …

Compared with orthogonal multiple access (OMA), non-orthogonal multiple access (NOMA)
has enormous advantages in enhancing fairness and spectral efficiency for downlink …

We study a downlink non-orthogonal multiple access (NOMA) system, in which a base
station (BS) serves a near user and a far user on the same frequency band simultaneously …

In uplink non-orthogonal multiple access (NOMA) channels, the existing cooperative
successive interference cancellation (SIC) and power control (PC) schemes lack the …

A novel device-to-device (D2D) aided cooperative non-orthogonal multiple access (NOMA)
scheme (termed as D2D-SG-NOMA) is proposed, where two similar gain (SG) near users …

Wireless-powered relaying based on backscatter communication has emerged as a viable
solution to extend the transmission range of energy-constrained nodes with improved power …

In this paper, we consider a coexisting network of cellular transmission and device-to-device
(D2D) communication, in which two users need to receive downlink signals from base …

NOMA is a promising radio access technique for next-generation wireless networks. In this
article, we investigate the NOMA-based cooperative relay network. We begin with an …

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