Non-orthogonal multiple access (NOMA) technique can potentially increase spectral
efficiency and improve the network capacity of wireless networks. Ergodic secrecy capacity …

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 …

A key feature of the non-orthogonal multiple access (NOMA) technique is that users with
better channel conditions have prior knowledge about the information of other weak users …

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 …

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

The secrecy performance of a nonorthogonal multiple access (NOMA) system is examined
in this study by employment of a dual‐hop decode‐and‐forward (DF) relay under existence …

In this paper, we analyze the secrecy performance of a cooperative communication wireless
system using nonorthogonal multiple access (NOMA) over α-μ fading channel. A new …

The secrecy outage probability (SOP) performance is investigated for a cooperative non-
orthogonal multiple access system under eavesdropping attack, where a base station …

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 …

In this paper, we investigate the secrecy outage performance of a typical cooperative
downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel …
