Abstract:

Laser communications offer a higher data rate than radio frequency communications for ground satellite links. When the laser beam transmitter through the atmosphere, clear-air turbulence induces serious phase distortions and fall that damage in the receivers. Adaptive optics (AO) is one of existing approaches of satellite laser communications treats wave front correction. The natural of AO systems is iterative and distributed solutions, as the natural of metaheuristic algorithms such as genetic algorithm (GA).
In this paper, we propose an algorithm for wavefront correction based on GA and AO in satellite-to-ground laser communication links. Our algorithm implemented in a simulation tool called Object-Oriented Matlab Adaptive Optics (OOMAO). The study of the results proves the application of GA in AO improves its performance in wavefront correction and by consequence improves the communication in satellite-to-ground laser links.
