AB The Fisher Snedecor (F-S) F distribution has recently been introduced as a tractableturbulence-induced (TI) fading model that fits well with the experimental data. This paper provides aperformance evaluation of a free-space optical (FSO) re-configurable intelligent surface (RIS)-assistedcommunications (ACs) link over the F-S F TI fading channels, assuming the intensity modulationdirect detection (IM  DD) technique. In particular, novel and closed-form (C-F) analytical expressionsfor the probability density function (PDF) and cumulative distribution function (CDF) of the end-toend signal-to-noise ratio (SNR) in terms of Gaussian hyper-geometric functions are efficiently derived.Capitalizing on the obtained results, novel C-F analytical expressions for the moment generatingfunction (MMGF), outage probability (OP), average bit error rate (BER) and ergodic channel capacity(Cgamma) of the FSO RIS-ACs system over the F-S F TI fading channels are provided and numericallyevaluated under the various TI fading severity conditions. Furthermore, the second-order (S-O)statistical expressions for the level crossing rate (LCR) and average fade duration (AFD) are obtainedand thoroughly examined for various FSO RIS-ACs system model parameters.
