Abstract

Free-Space Optics (FSO) have been emerging communication field because of several advantages like cost-effective, higher bandwidth, and license free. It is basically line of sight communication and more suitable for last mile connectivity. Signal degradation occurs mostly due to atmospheric interference like rain, fog, etc. Diversity is an efficient solution to overcome these effects. In this paper, we have applied the concept of combined diversity (spatial and wavelength) with help of two receiver antenna to mitigate effects of fog and rain attenuation over transmission. An Equal Gain Combining for array gain enhancement applied at the receiver side. Results also demonstrated improvement in BER performance under strong turbulence.
