Over the last few years, interference has been a major hurdle for successfully implementing
various end-user applications in the fifth-generation (5G) of wireless networks. During this …

Today's wireless networks allocate radio resources to users based on the orthogonal
multiple access (OMA) principle. However, as the number of users increases, OMA based …

In this correspondence, we investigate the physical layer security for cooperative
nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) and …

Intelligent reflecting surface (IRS) is a promising technology to enhance the coverage and
performance of wireless networks. We consider the application of IRS to non-orthogonal …

Non-orthogonal multiple access (NOMA) scheme is emerging as a favourable multiple
access scheme for future 5G networks. Compared to orthogonal multiple access techniques …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

The emerging non-orthogonal multiple access (NOMA), which enables mobile users (MUs)
to share same frequency channel simultaneously, has been considered as a spectrum …

Non-orthogonal multiple access (NOMA) is one promising technology, which provides high
system capacity, low latency, and massive connectivity, to address several challenges in the …

In this paper, we develop a non-orthogonal multiple access (NOMA)-based two-way relay
network with secrecy considerations, in which two users wish to exchange their NOMA …

In this paper, a full-duplex (FD) non-orthogonal multiple access (NOMA) scheme for a
cooperative relay sharing network (termed as FD-NOMA-RS) is presented, in which two …
