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.
