Design and investigation of multiple TX/RX FSO systems under different weather conditions

Abstract

In the proposed model, effect of number of transmitters and receivers on performance of proposed free-space optical (FSO) communication system is simulated as well as analyzed under various weather conditions like clear, haze and fog. FSO communication provides a strong and efficient method for transmission and reception of information through free channels because of its higher data transfer capacity and inbuilt ability of security. The effect of environmental parameters has been investigated for range of 1 km. The effect of attenuation increases in bad weather conditions affecting the performance of FSO system while designing a system the weather conditions have to be taken care. The effect is to beat the impact of fog attenuation on FSO system by assessment and execution through simulated results of the executed model with respect to Q factor, height of eye, power received and bit error rate. The proposed multiple TX/RX FSO system shows better results as compared to the 1 TX/1 RX system.
