چکیده
|
In this paper, we investigate the effects of auto-tracking subsystem together withdifferent beam divergences on snr, ber and stability of fso communication links. forthis purpose we compute the values of power, snr and ber on receiver, based on analyticformula of gaussian beam on receiver plane. in this computation the atmospheric effectsincluding absorption, scattering and turbulence are considered. using mentioned computedvalues, the laser link stability and its reliability in presence of auto-tracking subsystems areevaluated. the results of simulation and computation are shown with the help of figuresand tables.
