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 …

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 …

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

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

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

In this paper, we analyze the secrecy outage probability (SOP) and the fairness of average
packet transmission time for a non-orthogonal multiple access (NOMA) system which …

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 non-orthogonal multiple access (NOMA) systems, serving multiple users in shared
resource blocks can allow untrusted users to overhear the messages of other users. In this …

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 …

Both cooperative non‐orthogonal multiple access (NOMA) and physical layer security (PLS)
are promising techniques for future communication systems. This paper investigates the PLS …
