The ambitious high data-rate applications in the envisioned future beyond fifth-generation
(B5G) wireless networks require new solutions, including the advent of more advanced …

Abstract The Internet of Things (IoT) is expected to require more effective and efficient
wireless communications than ever before. For this reason, techniques such as spectrum …

This paper investigates a downlink multiple-input single-output intelligent reflecting surface
(IRS) aided non-orthogonal multiple access (NOMA) system, where a base station (BS) …

The explosive popularity of small-cell and Internet of Everything devices has tremendously
increased traffic loads. This increase has revolutionised the current network into 5G …

This paper investigates the secure transmission in a simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS) assisted uplink non-orthogonal …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

This letter investigates secure transmission in an intelligent reflecting surface (IRS) assisted
non-orthogonal multiple access (NOMA) network. Consider a practical eavesdropping …

With 5G mobile communication systems having been commercially rolled out, research
discussions on next generation mobile systems, that is, 6G, have started. On the other hand …

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

In this paper, we investigate the outage behavior of a simultaneously transmitting and
