This paper proposes a secrecy transmission for intelligent reflecting surface (IRS) assisted
non-orthogonal mul-tiple access (NOMA) network. Different from existing schemes with fixed …

Non-orthogonal multiple access (NOMA) and backscatter communications are considered to
be promising technologies due to their applications in large-scale Internet-of-things (IoT) …

A novel reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access
(NOMA) downlink transmission framework is proposed. We formulate a long-term stochastic …

Abstract Non-Orthogonal Multiple Access (NOMA) has already proven to be an effective
multiple access scheme for 5th Generation (5G) wireless networks. It provides improved …

This paper investigates intelligent reflecting surface (IRS)-assisted systems, where an
access point sends independent information to multiple users with the aid of one IRS. Our …

Reflecting intelligent surfaces (RIS) has gained significant attention due to its high energy
and spectral efficiency in next-generation wireless networks. By using low-cost passive …

The combination of simultaneously transmitting and reflecting-reconfigurable intelligent
surface (STAR-RIS) and nonorthogonal multiple access (NOMA) brings the necessary full …

In this paper, a novel simultaneously transmitting and reflecting reconfigurable intelligent
surface (STAR-RIS) assisted non-orthogonal multiple access (NOMA) system is proposed …

As for the time-division communications system, the pilot spoofing attack (PSA) technique is
maliciously utilized by active eavesdroppers during the uplink training phase, for …

Ambient internet-of-things networks are just emerging to support sixth-generation wireless
goals. We thus investigate a symbiotic radio (SR) system for a single-user primary network …
