In this study, the authors investigate the energy‐efficient (EE) relay selection (RS) and power
allocation (PA) in a cooperative secured system. Their scenario includes a multiple‐antenna …

Two opportunistic transmission schemes, ie, joint user-relay selection with beamforming
(JURS-BF) and joint user-relay selection with antenna selection (JURS-AS), are proposed …

In this study, the authors investigate the impact of channel estimation error (CEE) on the
performance of a multiple‐input–multiple‐output (MIMO) two‐way relay system under …

To protect data communication from eavesdropper nodes, different techniques have been
developed to improve the physical‐layer security (PLS) of communications systems …

Amplify-and-forward (AF) two-way relay networks (TWRNs) have become popular to provide
spectrally efficient communication when range extension or energy efficiency is needed by …

In this paper, for a two-way relay channel comprising two multi-antenna transceivers and L
single-antenna potential relay nodes, we propose three network-coded cooperative spatial …

In this paper, we investigate the performance of an amplify-and-forward multi-input multi-
output two way relay network where two sources are equipped with multiple antennas …

This paper investigates the outage performance of terahertz (THz) wireless communication
systems empowered with dual-hop amplify-and-forward (AF) relaying technology. In …

This paper investigates the impact of residual hardware impairments on the performance of
two-way communication systems empowered by a reconfigurable intelligent surface (RIS) …

In this paper, we investigate the ergodic sum rate (ESR) performance of a two-way relay-
assisted vehicular communication system. The overall information is exchanged between a …
