Non-orthogonal multiple access (NOMA) is considered as one of the most promising
technologies to handle the issue of spectrum scarcity in beyond fifth-generation (5G) …

Nonorthogonal multiple access (NOMA) represents a paradigm shift from conventional
orthogonal multiple-access (MA) concepts and has been recognized as one of the key …

This paper develops a tractable analysis framework to evaluate the reliability and security
performance of cooperative non-orthogonal multiple access (co-NOMA) in cognitive …

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 …

This letter investigates a joint antenna selection (AS) problem for a MIMO cognitive radio-
inspired non-orthogonal multiple access network. In particular, a new computationally …

The demands for high spectral efficiency and massive connections led the researchers to
investigate new multiple access techniques for the future wireless networks. Non-Orthogonal …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

This paper investigates the impact of residual transceiver hardware impairments (RTHIs) on
cooperative non-orthogonal multiple access (NOMA) networks, where generic fading …

Although the theory of nonorthogonal multiple access (NOMA) has been widely investigated,
so far, there is a lack of applying beamforming into NOMA systems. In this article, we …

In traditional cognitive radio (CR), secondary user (SU) can only access the idle spectrum
when primary user (PU) is absent, which has to vacate the spectrum when detecting the …
