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 …

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 …

Atmospheric turbulence induced fading is one of the main impairments affecting free-space
optics (FSO) communications. In recent years, Gamma-Gamma fading has become the …

PiN (PIN) diodes and avalanche photo-diodes (APD) are the most commonly used photo-
detectors in terrestrial FSO systems. In this paper, we review the photo-detection process for …

Atmospheric effects can significantly degrade the reliability of free-space optical
communications. One such effect is scintillation, caused by atmospheric turbulence, refers to …

A link budget for a deep-space optical channel depends in part on the choice of modulation
format and error-control coding scheme. This article describes several properties of the …

The main drawback in communicating via the free space optical (FSO) channel is the
detrimental effect the atmosphere has on a propagating laser beam. Atmospheric turbulence …

The effect of pointing errors on the average bit error probability (ABEP) of an intersatellite
laser communication link is studied. A closed-form expression in terms of the Marcum …

In this paper, we propose the idea of dynamic beam waist adjustment for laser inter-satellite
communications, and study the performance of this dynamic-beam scheme. The beam waist …

Terahertz (THz) band transmission has the potential to revolutionize future-generation
wireless networks by jointly meeting communication and non-communication demands of …
