@conference {Hajji2017, title = {Performance analysis of mixed Weibull and Gamma-Gamma dual-hop RF/FSO transmission systems}, booktitle = {Proceedings - 2017 International Conference on Wireless Networks and Mobile Communications, WINCOM 2017}, year = {2017}, note = {cited By 0}, abstract = {In this paper, we study the performance of a dualhop amplify-and-forward (AF) communication system over asymmetric links composed of Radio-Frequency (RF) and Free-Space- Optical (FSO) links in the presence of atmospheric turbulence as well as pointing error impairments under both heterodyne detection and intensity modulation with direct detection (IM/DD) techniques. The RF link is assumed to operate under Weibull fading, while the FSO channel undergoes Gamma-Gamma (GG) fading. Using a Channel-State-Information (CSI)-assisted relaying, we derive closed-form expressions for the cumulative distribution function (CDF) and the probability density function (PDF) of the end-to-end signal-to-noise ratio (SNR) for the considered system in terms of the Meijer G-function. Based on these results, a novel closed-form expression of the average symbol error rate (ASER) in terms of the bivariate Fox Hfunction is derived. Finally, numerical results are presented to validate the analytical expressions. {\textcopyright} 2017 IEEE.}, doi = {10.1109/WINCOM.2017.8238201}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85041443126\&doi=10.1109\%2fWINCOM.2017.8238201\&partnerID=40\&md5=7dcd13992ed3c88bd3b52b45e5c9ee66}, author = {Hajji, M. and El Bouanani, F.} }
