In a satellite-to-ground laser communication system, the presence of atmospheric turbulence
and residual angle of arrival fluctuations limit the efficiency with which the propagating beam …

Diversity reception is an effective technology to mitigate the atmospheric turbulence effect on
the performance of the coherent free-space optical (FSO) communications. Furthermore …

In order to eliminate the impact of atmospheric turbulence on the performance of free-space
optical (FSO) communication systems, the multi-aperture receiving technique is wildly …
