This paper proposes a novel non-orthogonal multiple access (NOMA)-based cooperative
transmission scheme for a spectrum-sharing cognitive radio network (CRN), whereby a …

Non-orthogonal multiple access (NOMA) is one of the promising radio access techniques in
5G communication networks. In this paper, a cooperative NOMA relaying scheme with two …

In this letter, a cooperative non-orthogonal multiple access system with imperfect successive
interference cancellation is investigated in an underlay cognitive radio network. Considering …

Non-orthogonal multiple access (NOMA) is regarded as a candidate radio access technique
for the next generation wireless networks because of its manifold spectral gains. A two …
