We focus on energy-efficient circular maneuvering and communication for a small
unmanned aerial vehicle (UAV)-based relay, acting as a communication relay for connecting …

In this paper, we propose general-order transmit antenna selection to enhance the secrecy
performance of multiple-input-multiple-output multieavesdropper channels with outdated …

This paper elaborates on the end-to-end capacity of dual-hop free-space optical (FSO)
communication systems employing amplify-and-forward (AF) relaying, assuming channel …

We investigate the secrecy performance of dual-hop amplify-and-forward multi-antenna
relaying systems over Rayleigh fading channels, considering the direct link between the …

Achieving reliable acoustic wireless video transmissionsin the extreme and uncertain
underwater environment is a challenge due to the limited bandwidth and the error-prone …

In this paper, a framework is presented to analyze the performance of multiuser diversity
(MUD) in multiuser point-to-multipoint (PMP) MIMO systems with antenna selection. Based …

In this Letter, tight closed-form approximations for the ergodic capacity of dual-hop fixed-gain
relaying systems are derived. Our analysis allows for independent Nakagami-m fading …

In this paper, we investigate the performance of a device-to-device (D2D) multiple-input and
multiple-output (MIMO) communications using an amplify-and-forward relaying for various …

In this paper, we study a hybrid interweave-underlay spectrum access system that integrates
amplify-and-forward relaying. In hybrid spectrum access, the secondary users flexibly switch …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …
