Space-air-ground integrated networks (SAGIN) within UAV-assisted free-space optical
(FSO) communication systems can efficiently accommodate massive connections and …

Physical transceivers have hardware impairments that create distortions which degrade the
performance of communication systems. The vast majority of technical contributions in the …

We study two-hop communication protocols where one or several relay terminals assist in
the communication between two or more terminals. All terminals operate in half-duplex …

Detection performance of an energy detector used for cooperative spectrum sensing in a
cognitive radio network is investigated over channels with both multipath fading and …

In this paper, we carry out a unified performance analysis of a dual-hop relay system over
the asymmetric links composed of both radio-frequency (RF) and unified free-space optical …

We consider three-node wireless relay channels in a Rayleigh-fading environment.
Assuming transmitter channel state information (CSI), we study upper bounds and lower …

Facilitating Cooperation for Wireless Systems Cooperative Communications: Hardware,
Channel & PHY focuses on issues pertaining to the PHY layer of wireless communication …

In this work, the performance analysis of a dual-hop relay transmission system composed of
asymmetric radio-frequency (RF)/free-space optical (FSO) links with pointing errors is …

This letter reports a performance analysis of a dual-hop relay system composed of
asymmetric radio-frequency and free-space optics (RF/FSO) links. This approach is based …

This paper presents novel results for the performance analysis of dual-hop free-space
optical/radio frequency (FSO/RF) transmission systems where the FSO link is modeled by …
