Abstract :
In spite of the technical development of the components, the major limitation of free-space laser communication performance is due to the effects of atmospheric turbulence. Major effects on the beam such as beam wander and beam scintillation degrade the performance at the receiver. In our analysis BER is determined at the receiver in different turbulence conditions for different transmitted laser beam widths. Aperture averaging technique is considered to improve the performance.
