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

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 …

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

In this correspondence, we investigate the physical layer security for cooperative
nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) and …

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 …

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 …

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 …

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

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

We study the secrecy transmission of uplink non-orthogonal multiple access (NOMA) with
single antenna and multi-antenna users in presence of an eavesdropper. Two phases are …
