Non-orthogonal multiple access (NOMA) has been a strong candidate to support massive
connectivity in future wireless networks. In this regard, its implementation into cooperative …

This paper investigates the performance of cooperative non-orthogonal multiple access (C-
NOMA) in downlink communication systems. Using C-NOMA, users with more favorable …

With the increasing demand for security in many sectors, such as defense and health
systems, developing secure Internet of Things (IoT) networks is a matter of great urgency …

A key feature of the non-orthogonal multiple access (NOMA) technique is that users with
better channel conditions have prior knowledge about the information of other weak users …

The incorporation of user-assisted cooperative relaying into beamspace massive multiple-
input multiple-output (mMIMO) non-orthogonal multiple access (NOMA) system can extend …

In this paper, we present analytical results on the effective capacity (EC) for a dual-hop
cooperative network employing non-orthogonal multiple access and the decode-and …

In this paper, we study a relay-aided multiuser amplify-and-forward relaying system where a
multi-antenna base station (BS) transmits downlink to multiple single-antenna mobile …

Selection strategies prove to be a valuable approach in mitigating complexity associated
with antenna selection (AS) and relay selection (RS), optimizing signal transmission through …

With the increasing demand of security for many sectors, such as defense and health
systems, developing secure Internet of Things (IoT) networks is a matter of great urgency …

Cooperative communication is an appealing technique stemming from the information-
theoretic notion of cooperative diversity and having gradually evolved into a mainstream …
