Performance improvement of FSO communication system using MIMO technique

Abstract

In proposed simulation model, the effect of different MIMO system has been analyzed on performance of free space optical (FSO) system concealed by various climatic conditions like clear, haze and fog. FSO is a free space communication system where space acts as medium between transceivers which provides a strong and efficient method for transmission and reception of information. The effect of different weather conditions has been investigated for range of 1 and 2 km at frequency 193.1 GHz. The proposed MIMO-FSO simulation system has been analyzed for different parameters like Q factor, height of eye, power received and bit error rate. The desi gned 4X4 MIMO-FSO system provides better results as compared to the 2X2MIMO and SISO-FSO system.
