Reduction Of Effect Of Atmospheric Turbulence In FSO Communication

Astha Puri, Rishabh Jain

FSO communication is used to communicate between ground and satellite links wirelessly through free space. The transmission of data gets affected due to various atmospheric turbulence regimes. This causes degradation in both the intensity as well as the phase of the received signal. Over the time different methods have been implemented in order to minimize these affects. The main objective of this paper is to prepare a comparison between the performances of two such methods: (i) Aperture averaging (ii) Employing multiple transmitters and receivers and also try combining the two for better performance. The comparison will be done on the basis of received power and BER. The simulations will be performed in Optisystem 7.0 by Optiwave. In the first phase, the theoretical calculations for both the methods will be performed and the simulation model will be prepared. The second phase will be about analyzing both the methods under different conditions and preparing a comparison between the two. The analysis will lead to the conclusion of which method is better over the other based on the above parameters.
