Survey on Free Space Optical Communication: A Communication Theory Perspective
IEEE Communications Surveys and 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.
