This review paper discusses the complete evolution of free-space optical (FSO)
communication, also known as unguided optical communication (UOC) technologies, all the …

There is a continuing growth in the demand for data bandwidth, and the multiplexing of
multiple independent data streams has the potential to provide the needed data capacity …

The next generation (NG) optical technologies will unveil certain unique features, namely
ultra-high data rate, broadband multiple services, scalable bandwidth, and flexible …

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 …

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 …

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 recent studies, the average capacity for optimal rate adaptation (ORA) of free-space
optical channels in turbulent atmosphere has been derived in closed form, mainly based on …

In this paper, we propose a new probability distribution function which accurately describes
turbulence-induced fading under a wide range of turbulence conditions. The proposed …

We investigate the outage probability and the average bit error rate (BER) performance of a
dual-hop amplify-and-forward (AF) relaying system, composed of a mixed radio frequency …

This survey article discusses the revolutions of wireless communication technologies right
from the prehistoric man's fire signals to today's space optical communications. A brief …
