Performance analysis of N-Fisher-Snedecor F fading and its application to N-Hop FSO communications [proceedings]. 17th International Symposium on Wireless Communication Systems (ISWCS 2021), Berlin, Germany.978-1-7281-7432-7https://hdl.handle.net/10016/36630Proceedings of: 17th International Symposium on Wireless Communication Systems (ISWCS 2021), 06-09 September 2021, Berlin, Germany.The Fisher-Snedecor F distribution has been recently proposed as an experimentally verified and tractable turbulence induced fading model (TIFM) for free space optical (FSO) communications. This paper provides outage probability (OP) and higher-order (HO) performance analysis of the product of N independent but not identically distributed (i.n.i.d) Fisher-Snedecor F random variates (RVs). Accurate and closed-form (C-F) expressions for cumulative distribution function (CDF), level crossing rate (LCR) and average fade duration (AFD) of N-Fisher-Snedecor F distribution are successfully derived. The general property of a Laplace approximation approach for evaluation of N-folded complex integral-form (I-F) LCR expressions has been applied. The obtained statistical results are directly related to the performance evaluation of N-hop FSO communication links over weak, moderate and strong atmospheric turbulence conditions.6eng© 2021, IEEEFisher-snedecor F distributionFSO communicationsHigher order statisticsOutage probabilityconference proceedingsTelecomunicacioneshttps://doi.org/10.1109/ISWCS49558.2021.9562174open access162021 17th International Symposium on Wireless Communication Systems (ISWCS)CC/0000032810
