The strictly positive secrecy capacity (SPSC) performance is examined in a new design of
non-orthogonal multiple access (NOMA) considered in this study. This system model …

This paper investigates secure transmission for non-orthogonal multiple access (NOMA)
systems where the imperfect successive interference cancellation (SIC) is considered at …

In this article, we propose a novel cooperative non-orthogonal multiple access (NOMA)
scheme to guarantee the secure transmission of a specific user via two time slots. During the …

This paper studies the impacts of antenna selection algorithms in decode‐and‐forward (DF)
cooperative nonorthogonal multiple access (NOMA) networks, where the secure information …

In 5G wireless communication networks, Non-Orthogonal Multiple Access (NOMA) has
attracted much attention in recent years. This paper investigates physical layer security of a …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same frequency band to improve the spectral efficiency. Whereas a security flaw emerges in …

In this paper, a down-link non-orthogonal multiple access (NOMA) system with imperfect
successive interference cancellation (SIC) using Energy-Harvesting untrusted relays is …

We introduce the cooperative full-duplex relaying to a downlink non-orthogonal multiple
access (NOMA) system and analyze the secrecy performance of each NOMA user. In …

This paper investigates the security performance of two relay selection schemes for
cooperative non-orthogonal multiple access (NOMA) systems, where K randomly distributed …

In this paper, we investigate the secrecy performance of an Amplify-and-Forward (AF) relay
in a cooperative NOMA system. The AF relay ensures the transmission of the signal in the …
