Abstract

Large apertures are used in FSOC systems to increase signal and reduce scintillation. Based on simulations of a realistic FSOC system using a Gaussian beam we found significant changes in the empirical PDF with increasing aperture size. We compare the fit of PDFs to data and the effect of PDF choice on <BER> and fade probability of a direct detection FSOC system.
