Mitigation of Atmospheric Turbulence in Free Space Optics: A Review

Abstract

This paper reviews the work done for modeling and mitigating the effect of atmospheric turbulence and fog in the Free Space Optics (FSO). The various models proposed in recent times have been discussed and analyzed. The strengths and weaknesses of the scheme have been highlighted, providing the reader with a well rounded holistic picture of the work done in this area. The paper discusses an example to show the best mitigation technique related to Signal to noise ratio and Bit error rate (BER) based on data mining results.
