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.

Optical Engineering, 2018
The fiber-coupling efficiency of a satellite-to-ground (STG) downlink laser communication system is particularly influenced by atmospheric turbulence, thereby reducing the communication performance significantly. We report on a highly reliable ground equivalent verification to demonstrate the atmospheric turbulence effects on the fiber-coupling ...

Statistical distribution of fiber-coupling efficiency in the satellite-to-ground downlink
Optical Engineering, 2011In the satellite-to-ground downlink lasercom systems, efficient coupling of atmospherically distorted spatial light into single-mode fibers is a key technology for fiber-coupled optical receiver. Statistical distribution of fiber-coupling efficiency is important to analyze the performance of a receiver.
