In this paper, the average symbol error of multi-hop free space optical communication system is analyzed using Exponentiated Weibull distributed channel. Error performance is analyzed using average symbol error rate for M-QAM subcarrier intensity modulation with direct detection technique. Considering the aperture averaging effect, for various finite receiver sizes, the performance of the system for different number of hops is analyzed under different atmospheric turbulence conditions. © 2020 IEEE.
