| Video Discription | The deployment of visible light communication system is hampered by the presence of large amount of environmental noise caused by the use of artificial lighting and/or solar radiations, depending on the specific scenario, is one of the main challenges to be tackled to achieve a full fledged deployment of VLC in realistic scenarios. For mitigation of noise it is essential to design effective digital filtering stage to recover optical signal from background noise. In this paper we have presented a novel digital signal processing filtering stage based on Software Defined Radios. The SDR filtering stage is then integrated with a previously developed low cost Arduino DUE-based VLC system, in order to compare the performances of the two systems. The system employs standard low-power automotive white LED lamps, and it is tested for baud rates up to 1 Mbaud (OOK) Manchester. Our measurements, show that the DSP stage brings a 10-times improvement in intrinsic sensitivity as compared to the original system. This solution is effective for broad band light sources, like white LED, as it is not possible to exploit optical filtering in these scenarios.
