Optics Communications, 2021
Abstract The satellite-to-ground communications systems are a significant part of the future communications network. Meanwhile, the large capacity is also one of the goals pursued by the communications network community. In this context, the free-space optical (FSO) communications technique is a prospective solution for satellite-to-ground ...

Laser Communication and Propagation through the Atmosphere and Oceans X, 2021
By enabling Free Space Optics (FSO) technology as complementary solution to RF systems, the next generation satellite communication that relies on optical links is on the verge. Even though the transition to wireless optical communication is a fact, the space domain is very conservative to such critical changes that call for close evaluation of each ...

SPIE Proceedings, 2016
The performances of satellite-to-ground downlink optical communications over Gamma-Gamma distributed turbulence are studied for multiple apertures receiver system. Maximum ratio combining (MRC) technique is considered as a combining scheme to mitigate the atmospheric turbulence under thermal noise limited conditions.

Spatial diversity can be used over satellite-to-ground optical links to mitigate turbulence induced fading. In this paper, bit-error rate (BER) performances of satellite-to-ground downlink optical communication are evaluated for fiber-based coherent detection receiver system with spatial diversity.

We analyze the performance of a satellite-to-ground downlink coherent lasercom system taking into account the combined effects of atmospheric wavefront aberration and tracking error of the receiver. We revise the wavefront phase variance in the case where the tracking error of the receiver terminal is present.
