Atmospheric turbulence can cause a significant performance degradation in free-space optical communication systems. It is well known that the effect of turbulence can be reduced by performing aperture averaging and/or employing spatial diversity at the receiver. In this paper, we provide a synthesis on the effectiveness of these techniques under different atmospheric turbulence conditions from a telecommunication...
Atmospheric turbulence can cause a significant performance degradation in free space optical (FSO) communication systems. We investigate the impact of aperture averaging on the performance of FSO systems under different atmospheric turbulence regimes. Performance evaluation is made in terms of the average bit-error-rate. In particular, we bring clearance on the impact of propagation model on the benefit...
