FSO System Performances for Novel Turbulence Shadowed Chi-square Model

Abstract

This paper presents a novel shadowed Chi-square model for the probability density function (PDF) of free space optics (FSO) channel irradiance fluctuations. The performance of the on-off keying (OOK) modulated FSO system in the presence of atmospheric turbulence and misalignment fading is analyzed, determining the ABER at the receiving side in relation to average optical power. The results are shown graphically and discussed to understand the effect of turbulence and other parameters on the received signal quality in the OOK modulated FSO system.
