Abstract

In this paper, we have presented analysis of 10 Gbit/s OFDM based FSO communication system using MQAM, under different weather condition and reported the improved performance by usage of a preamplifier and square root module (SQRT). A distance of 1800 m was achieved with the same performance as without SQRT representing an enhancement of 90 %.
