We investigate the optimal signal detection problem in large-scale multiple-input multiple-
output (MIMO) system with the generalized spatial modulation (GSM) scheme, which can be …

In this paper, we demonstrate that despite the power constraints on all transmit nodes
caused by the interference temperature limit (ITL) imposed by the primary user, power …

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

This paper investigates the performance of non-orthogonal multiple access (NOMA)-based
coordinated direct and relay transmission (CDRT) networks with short-packet …

This paper proposes a new scheme to enhance the secrecy performance of non-orthogonal
multiple access (NOMA)-based coordinated direct relay transmission (CDRT) systems with …

In this paper, we propose a two-way relaying scheme using digital network coding in an
underlay cognitive radio network. In the proposed scheme, the transmit antenna selection …

Overlay networks allow the unlicensed transmitter (UT) to aid the licensed transmitter (LT) by
sending the superimposed signal including messages of both UT and LT with a higher …

The paper presents performance analysis of a multiuser Cooperative Non-Orthogonal
Multiple Access (CNOMA) network that is underlay to a primary network. A selected …

In overlay networks, the cognitive sender (CS) assists the primary transmitter (PT) by
broadcasting the superposed signal composed of both cognitive and primary information …

This paper analyses the performance of the uplink multiple-input single-output (MISO)
reconfigurable intelligence surface (RIS)-based system. Aiming to improve the user's uplink …
