“…In free-space optical (FSO) communication, the transmitted light responds to the influence of perturbations in their surroundings. An FSO technique has been developed for transmitting and receiving signals without significant loss [1]. FSO transceivers are designed to provide high-speed, free licensed, and secured communication system [2].…”

In this study, the multiple-input multiple-output (MIMO) technique is proposed to mitigate the influence of an external electric field on the free space optical (FSO) communication. The main advantages of the proposed technique are: decrease the attenuation (decrease bit error rate BER), improve data transmission at all divergence angles, and increase the quality (Q-factor) (even when it decreases at higher divergence angles). The importance of these results can be used to solve the problem of electric discharges that occurs on power transmission lines that interfere with the optical wireless system.

“…Radio communication systems do not function reliably under these conditions due to the limitations in capacity and scalability [6]. Free-space optical (FSO) signal is used to enable transmission and receiving of signals without significant loss [7]. It has the ability and durability to transfer large amounts of energy.…”

This study estimates the performance of a free space optical system (FSO) affected by air pollutants from oil fires. Simulations are performed to evaluate the reliability of optical propagation according to the length of the FSO channels under two beam angle angles. The proposed FSO system parameters such as the Q-factor, BER and reception capacity are successfully used to reduce channel loss. Results demonstrate that the proposed FSO link performs satisfactorily when the divergence angle is 1 mrad and the distance is from 0.5 km to 0.9 km. Q-factor and receiving power decrease when the divergence angle of beam increases to 2 mrad, and a link is achieved when the distance is from 0.5 km to 0.7 km. The eye diagram is used to evaluate and confirm the quality of received data. An eye opening is observed at 0.5 km for both divergence angles. Then, the eye completely closes at 1 km for 2 mrad, thereby degrading the performance. Therefore, these results can be conducted for similar systems optimization options by applying our analysis
