Evaluation of the strong turbulence impact over free-space optical links

This work expands the study of the impact of the atmospheric scintillation phenomenon in a free-space optical (FSO) communication system. Its behavior is evaluated by means of the bit error rate (BER). The contribution of our work is the BER calculation of the FSO system for different system parameters through simulations of the link combined to the already established scintillation model as the gamma–gamma model. The results show how a FSO link can be impacted by any turbulence regime.
