This paper investigates the reliability and security performance of the downlink non-
orthogonal multiple access (NOMA) networks over Nakagami-m fading channels, where the …

In this paper, an Internet-of-Things (IoT) system containing a relay selection is studied as
employing an emerging multiple access scheme, namely non-orthogonal multiple access …

Nonorthogonal multiple access (NOMA) is expected to be a promising technique for future
wireless networks. In this letter, we investigate the secrecy sum rate optimization problem for …

In this article, we study the secure communication performance of nonorthogonal multiple
access (NOMA) communication systems with aerial eavesdroppers. First, the ground-to …

In this letter, the ergodic performance of a non-orthogonal multiple access (NOMA) system
with untrusted users and imperfect successive interference cancellation based decoding is …

Semi-grant-free (SGF) transmission scheme enables grant-free (GF) users to utilize resource
blocks allocated for grant-based (GB) users while maintaining the quality of service of GB …

This letter investigates secure transmission for a cooperative non-orthogonal multiple
access (NOMA) network consisting of multiple near users (NUs), a far user (FU) and an …

Serial interference cancellation (SIC) technology is the key to ensure a higher system
capacity for NOMA. However, SIC may also introduce some critical security risks, since it …

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 consider a multi-input multioutput (MIMO) nonorthogonal multiple access
(NOMA) network consisting of one source and two legitimate users (LUs), so-called near …
