In this letter, we investigate the ergodic secrecy sum rate of a two-way relay NOMA system.
In particular, by considering decode-and-forward signal processing at the relay and …

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

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 …

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 study the secrecy outage probability (SOP) and the strictly positive secrecy
capacity (SPSC) of cooperative non-orthogonal multiple access (NOMA) system with a …

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 propose secure relaying transmission protocols using rateless codes,
where a source sends encoded packets to two intended destinations via help of …

For the security challenges generated by the eavesdroppers existing in wireless
communication systems, we propose a model for securely exchanging data between two …

Due to the inherent broadcast characteristics of wireless communications, the data
transmission is difficult to be shielded from unintended recipients. Secure communications …

Non-orthogonal multiple access (NOMA) has been envisioned as a promising multiple
access technique to improve spectral efficiency and provide massive connectivity in future …
