Characterization of Link for Free-Space Terrestrial Optical Communications in Côte d’Ivoire

Douatia Koné, Niangoran Medard Mene, Aladji Kamagaté


We investigate the availability of a terrestrial free-space optical communication system under different levels  of  atmospheric  turbulence  in  Côte d’Ivoire.  Thanks  to  the Gamma-gamma distribution, nature of the turbulence and its effects on the optical link have been explored in five sites, which represent different atmospheric and meteorological conditions  in  Côte d’Ivoire d’Ivoire  (Abidjan,  Bouaké,  Korhogo,  Man,  and  Bondoukou).    The nature of atmospheric turbulence in our environments was described using an assessment of the refractive index structure parameter. An analysis of error probability was conducted  across various environments. It was discovered that the deterioration of the signal caused  by atmospheric conditions in the typical circumstances of Cˆote d’Ivoire is not particularly substantial. Additionally, the height of the environment significantly impacts the nature of atmospheric turbulence.


Keywords: Error Probability; FSO; Gamma-gamma distribution; K distribution; Log-Normal distribution; SNR; Côte d’Ivoire.
