Abstract
Abstract—In recent years, free space optical (FSO)
communication has gained significant importance owing to
its unique features: large bandwidth, license free spectrum, high
data rate, easy and quick deployability, less power and low
mass requirements. FSO communication uses optical carrier
in the near infrared (IR) band to establish either terrestrial
links within the Earth’s atmosphere or inter-satellite/deep
space links or ground-to-satellite/satellite-to-ground links. It
also finds its applications in remote sensing, radio astronomy,
military, disaster recovery, last mile access, backhaul for
wireless cellular networks and many more. However, despite
of great potential of FSO communication, its performance is
limited by the adverse effects (viz., absorption, scattering and
turbulence) of the atmospheric channel. Out of these three
effects, the atmospheric turbulence is a major challenge that
may lead to serious degradation in the bit error rate (BER)
performance of the system and make the communication link
infeasible. This paper presents a comprehensive survey on
various challenges faced by FSO communication system for
ground-to-satellite/satellite-to-ground and inter-satellite links. It
also provide details of various performance mitigation techniques
in order to have high link availability and reliability. The first
part of the paper will focus on various types of impairments
that pose a serious challenge to the performance of optical
communication system for ground-to-satellite/satellite-to-ground
and inter-satellite links. The latter part of the paper will provide
the reader with an exhaustive review of various techniques
both at physical layer as well as at the other layers (link,
network or transport layer) to combat the adverse effects of
the atmosphere. It also uniquely presents a recently developed
technique using orbital angular momentum for utilizing the high
capacity advantage of optical carrier in case of space-based and
near-Earth optical communication links. This survey provides
the reader with comprehensive details on the use of space-based
optical backhaul links in order to provide high capacity and
low cost backhaul solutions.
