Abstract :
In this paper, we investigate the effects of auto-tracking subsystem together with
different beam divergences on SNR, BER and stability of FSO communication links. For
this purpose we compute the values of power, SNR and BER on receiver, based on analytic
formula of Gaussian beam on receiver plane. In this computation the atmospheric effects
including absorption, scattering and turbulence are considered. Using mentioned computed
values, the laser link stability and its reliability in presence of auto-tracking subsystems are
evaluated. The results of simulation and computation are shown with the help of figures
and tables.
