WITHDRAWN: Enhancement the performance of FSO communication system under atmospheric turbulence

Abstract

Abstract (FSO) Frees Space Optical communication is considered one of the communication systems types which uses light to carry the data between transmitter and receiver. It is previously known that the system which uses single input single output (SISO) technique is suffered from high rate of attenuation due to obstacles and various conditions of weather. The impacts of weather conditions which influence on the performance of the overall FSO communication system. Wavelength division multiplexing (WDM) is vastly utilized in FSO communication to take advantage of channel capacity with high efficiency. Multiple input multiple output (MIMO) is used in FSO systems to maintain perfect availability of transmission path. The study is proposed represent by integration between WDM and MIMO techniques to get FSO-WDM-MIMO system to enhance the performance of FSO communication system. Also in this study Comparison between the proposed system and the normal FSO-WDM system is made in terms of quality factor and transmission range under different weather attenuation. The proposed system FSO-WDM-MIMO system shows promising results in the performance and the quality of the received signal. The enhancement is achieved in transmission range, received power of optical signal, best quality factor, minimum bit error rate (BER) under different weather conditions.
