摘要：Solar light noise, as the main part of channel noise in outdoor visible light communication (VLC) system, would easily saturate the photon-detector, and dramatically decrease the outdoor VLC system performance. A Hilbert-Huang Transformation based solar light noise suppression method is proposed in this paper, a background light noise measurement system is also designed and implemented to verify the noise suppression method's performance. And the measurement result shows that it could effectively reduce the solar light noise, and improve the VLC system's stability and reliability.
