In this paper, we propose a proof of concept for the software defined-based free space optical communication (FSO) using GNU radio eco-system. We present a highly reconfigurable real-time FSO system to emulate the atmospheric conditions for the medium-to-long transmission range. Using an experimental testbed, we validate the proposed concept utilizing universal software radio peripherals. We show that the software defined FSO system offers greater flexibility, less complexity, and provides real-time signal processing results without the need to change the architecture of the hardware and the physical link space. The system performance is evaluated in terms of the estimated bit error rate under fog and turbulence conditions for 200 m link span.
