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 …

In this paper, we investigate the joint resource allocation for the non-orthogonal multiple
access (NOMA)-enhanced relaying networks involving the subcarrier pair, subcarrier-user …

The non-orthogonal multiple access (NOMA) schemes, where the users are allowed to
share the same time-frequency resource, have recently received a major interest to meet the …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient multiple access
technique for the fifth generation (5G) wireless networks. In this paper, we propose a …

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 …

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 this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
