Active reconfigurable intelligent surface (RIS) is deemed a prospective candidate to
compensate the double fading attenuation caused by the passive RIS, where each element …

The massive connectivity requirement and security issues have become major factors
restricting the further development of the Internet of Things. Nonorthogonal multiple access …

Intelligent reflecting surface (IRS) is deemed a promising technique for future wireless and
mobile technologies due to its ability to reconfigure the radio propagation environment. In …

Security is an issue in non-orthogonal multiple access (NOMA) and partial-NOMA because a
user may decode the message of its paired-user with which it shares a resource element …

In this paper, we consider a cooperative non-orthogonal multiple access (NOMA) system
with imperfect successive interference cancellation over Nakagami-m fading channel. We …

The recent integration of backscatter communication (BC) with power‐domain non‐
orthogonal multiple access (P‐NOMA) has triggered significant research interest due to its …

This study seeks an answer for the impact of the co-channel interference on the leakage rate
of illegitimate relay-assisted power-domain non-orthogonal multiple access (NOMA) …

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 …

We have proposed and analyzed secrecy performance of a network architecture which
contains a source, two destinations, a friendly jammer (FJ) and an eavesdropper (Eve). To …
