Reliability analysis of the auto-tracked FSO communication links
The effects of auto-tracking subsystems on the bit-error-rate (BER) and reliability of free-space optical (FSO) communication links are investigated. Based on Gaussian beam formula on the receiver plane and considering the atmosphere losses due to absorption, scattering and atmospheric turbulence numerical values for Power In Bucket (PIB), Signal to Noise Ratio (SNR) and BER are calculated. Using above mentioned values, the role of auto-track subsystems on link reliability improvement is described. The results are illustrated by graphs obtained by calculation and simulation.
