This paper introduces the hybrid-decode-amplify-forward (HDAF) cooperative relaying into a
control jamming aided NOMA network under Rayleigh-flat-fading channel conditions. In …

In this work, the secrecy of a typical wireless cooperative dual‐hop non‐orthogonal multiple
access (NOMA)‐enabled decode‐and‐forward (DF) relay network is investigated with the …

To enhance the secrecy of wireless transmission, we propose a cooperative user relaying
NOMA scheme, in which the near user works in full-duplex mode by transmitting jamming …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …

We study secure communications with an untrusted relay for a cooperative non-orthogonal
multiple access (NOMA) system, where a base station (BS) serves a near user (NU) and a …

The two-way relaying (TWR) technique has been confirmed to achieve higher spectral
efficiency and average sum rate compared with the one-way relaying (OWR) technique in …

We investigate physical layer security of a downlink cooperative non-orthogonal multiple
access system with an untrusted relay. A friendly jammer (FJ) is employed in order to …

In this letter, we consider a non-orthogonal multiple access (NOMA) network with a half-
duplex (HD) decode-and-forward (DF) relay to improve physical layer security (PLS) of two …

The application of successive interference cancellation (SIC) introduces critical security risks
to cooperative non-orthogonal multiple access (NOMA) systems in the presence of …

Non-orthogonal multiple access (NOMA) is an important technology for the forthcoming 5 G
and beyond. However, its privacy often suffers from adversarial eavesdropping, especially …
