This paper studies the application of non-orthogonal multiple access (NOMA) to a
cooperative multicast system (termed CM-NOMA). In particular, the multicast subscribers are …

In this paper, we study resource allocation problems for a two-tier cognitive heterogeneous
network in interweave spectrum sharing mode. Secondary users (SUs) in small cells (SCs) …

This paper investigates reconfigurable intelligent surface (RIS)-aided cognitive non-
orthogonal multiple access (NOMA) systems, where an RIS is deployed to serve two users …

Presently, Non-Orthogonal Multiple Access (NOMA) frequently uses Successive Interference
Cancellation (SIC) with channel estimation to detect the receivers' signal successfully …

This correspondence paper considers a dual-hop underlay cognitive radio nonorthogonal
multiple access (NOMA) network. The end-to-end outage probability (OP) is evaluated as …

In this letter, we propose a novel dynamic power allocation scheme for hybrid non-
orthogonal multiple access (DH-NOMA). The exact expressions for the outage probabilities …

Energy Efficiency (EE) is a significant problem for Cognitive Radio (CR) network. Recently,
more interest has focused on EE optimization problem in wireless-powered communication …

Abstract The Cooperative Non-orthogonal multiple access (C-NOMA) technique has been
considered as a promising solution to improve the coverage extension and transmission …

Physical layer network coding (PNC) has been proposed for information exchange between
a pair of users assisted by a relay. However, the spectral efficiency of PNC reduces when …

In non-orthogonal multiple access (NOMA) systems, the outage is regarded to happen when
a user cannot correctly decode the messages for users with higher decoding order and …
