The technology can be incorporated into satellites, drones or even. Channel fading due to atmospheric turbulence-induced scintillation for both with and without transmitter diversity is mathematically modeled. Free-Space Optical Communication (FSOC) uses laser beams to transmit data wirelessly. In addition, this thesis focuses on the analysis of signal fading due to the atmospheric turbulence mitigating technique using transmitter path diversity schemes. In the framework of this thesis, channel fading due to atmospheric turbulence is investigated in the ground-to-satellite communication scenario. However, exploiting the transmitter path diversity scheme with either wavelength division multiplexing or polarization division multiplexing mitigates the signal fading effect in the atmosphere and thus the system performance is improved. Here, the system performance can be degraded severely due to optical signal distortion through a random medium in the atmosphere. The large amount of data generated by the UAVs requires high data rate connectivity, thus making FSO communication very. With further development, possible applications include. Communication may be fully in space (an inter-satellite laser link) or in a ground-to-satellite or satellite-to-ground application. FSO technology leads vast modulation bandwidth, unlicensed spectrum, cost. The principles of transmission through free space optics (FSO) are the same as for the transmission of a signal through a fibre optic. UAVs are a possible future application for both civil and military use. NASA has developed a new laser beam pointing technology for use in space optical communications. Laser communication in space is the use of free-space optical communication in outer space. Free space optical (FSO) communication is an upgraded supplement to existing wireless technologies. Currently, the reliability of the free space optical link through which the optical beam propagates is a critical research issue. This chapter discusses the emerging technology of unmanned aerial vehicle (UAV)-based free-space optical (FSO) communication links. Long haul communications such as ground station to satellite communications, satellite-to-satellite communications and HDTV terrestrial broadcast communications are some of the possible FSO communication links. Free space optical communication provides wireless broadband services that could not be affordable by the current radio frequency (RF) communication links. ![]()
