Due to the unprecedented growth of high speed multimedia services and diversified
applications initiated from the massive connectivity of IoT devices, 5G and beyond 5G (B5G) …

Optical wireless communication (OWC) refers to transmission in unguided propagation
media through the use of optical carriers, ie, visible, infrared (IR), and ultraviolet (UV) bands …

With the ever-increasing demand for data and the radio frequency spectrum becoming
congested, free space optics (FSO) may find a niche for situations where fiber is too …

In this work, we present a unified performance analysis of a free-space optical (FSO) link that
accounts for pointing errors and both types of detection techniques ie, intensity …

The performance of free-space optical (FSO) communication systems is compromised by
atmospheric fading and pointing errors. The pointing errors are widely considered as a …

Optical communication is an integral part of the modern economy, having all but replaced
electronic communication systems. Future growth in bandwidth appears to be on the horizon …

The bit error rate (BER) performance of the free space optical (FSO) link suffers from the
atmospheric turbulence. By employing additional transmit and receive apertures at the …

In this paper, we present relay-assisted transmission as a powerful fading mitigation tool for
free-space optical systems operating in atmospheric turbulence channels. We study both …

Abstract Free Space Optical communication (FSO) is a wireless communication technology
which uses light to transmit the data in free space. FSO has advantages like unlicensed …

In this article we propose the use of the so-called Fisher-Snedecor-distribution to model
atmospheric turbulence-induced fading in free space optical communication systems. The …
