As a revolutionary paradigm for green communication architecture for the next-generation
communication system, reconfigurable intelligent surfaces (RISs) have been considered a …

In this paper, we explore a novel approach of using a simultaneous transmission and
reflection reconfigurable intelligent surface (STAR-RIS) to aid a multi-user (MU) multi-input …

Radio frequency (RF) signals can be relied upon for conventional wireless information
transfer (WIT) and for challenging wireless power transfer (WPT), which triggers the …

This study proposes the integration of a cooperative non-orthogonal multiple access
(CNOMA) and improved hybrid simultaneous wireless information and power transfer (IHS …

In this work, we investigate the performance of a reconfigurable intelligent surface (RIS)-
aided multi-user simultaneous wireless information and power transfer (SWIPT) network …

The combination of Non-orthogonal multiple access (NOMA) and Simultaneous wireless
information and power transfer (SWIPT) is an emerging technology that can meet the …

It is known that when the direct links between the base station (BS) and the users exist and
are nonnegligible, consolidating direct links could significantly enhance the performance of …

Non-orthogonal multiple access (NOMA) technique in cooperative system with energy
harvesting is investigated. A decode-and-forward (DF) relay is used to send messages from …

Rate-splitting multiple access (RSMA) and reconfigurable intelligent surface (RIS) have
been both recognized as promising techniques for 6G. The benefits of combining the two …

In this paper, we investigate the performance of intelligent reflecting surface (IRS) aided
cooperative non-orthogonal multiple access (NOMA) system in an energy-harvesting (EH) …
