Survey on Free Space Optical Communication: A Communication Theory Perspective
IEEE Communications Surveys & Tutorials, 2014 Optical wireless communication (OWC) refers to transmission in unguided propagation media through the use of optical carriers, i.e., visible, infrared (IR), and ultraviolet (UV) bands. In this survey, we focus on outdoor terrestrial OWC links which operate in near IR band.

Relay-assisted free-space optical communication [PDF]
IEEE Transactions on Wireless Communications, 2007 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 serial (i.e., multi-hop transmission) and parallel (i.e., cooperative diversity) relaying encoupled with amplify-and-forward and decode-and-forward modes.

Free Space Optical Communication Systems [PDF]
, 2009 The main advantage of using optical frequencies in free-space communication systems is the high directivity of the propagating optical beam. (In the context of this chapter, the term “free space” refers to unguided optical communications; exoatmospheric environments are referred to as “space.”) When transmitted from an antenna, electromagnetic waves ...

Crosstalk Suppression in Structured Light Free-Space Optical Communication
IEEE Open Journal of the Communications Society, 2020 Using space as an additional degree of freedom is one possible solution to cope with future bandwidth issues. In free-space optics (FSO), spatial multiplexing of structured light modes is limited by the impact of the atmospheric turbulence.
