Multi-channel Optical Wireless Communication under the Effect of Low Electric Field
Keywords:Free Space Optics, electric fields effect, multi-channels
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.
