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 …

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 …

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 …

In a downlink non-orthogonal multiple access (NOMA) system, the reliable transmission of
cell-edge users cannot be guaranteed due to severe channel fading. On the other hand, the …

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 …

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

This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time …

This paper analyzes the secrecy capacity of a cooperative relaying system using non-
orthogonal multiple access (NOMA). A new cooperative NOMA scheme is proposed, where …
