RSSI Probability Density Functions Comparison Using Jensen-Shannon Divergence and Pearson Distribution

The performance of a free-space optical (FSO) communications link suffers from the deleterious effects weather conditions and atmospheric turbulence. In order to better estimate reliability availability an FSO link, suitable distribution needs be employed. accuracy this model depends strongly on turbulence strength which causes scintillation effect. To end, variety probability density functions were utilized channel according refractive index structure parameter. Although many theoretical models have shown satisfactory performance, in reality they can significantly differ. This work employs information theoretic method, namely so-called Jensen–Shannon divergence, symmetrization Kullback–Leibler measure similarity between different distributions. doing so, large experimental dataset received signal measurements real is utilized. Additionally, Pearson family continuous distributions also employed determine best fit mean, standard deviation, skewness kurtosis modeled data.
