This letter reports the first experimental results obtained from a recently proposed single-photodiode receiver for visible light communications (VLC) using color shift keying (CSK) modulation. This novel detection scheme has the potential to reduce the implementation cost by two-thirds compared to the CSK-based receiver structure introduced in the VLC IEEE 802.15.7 standard. A proof of concept is performed to demonstrate its practical feasibility and advantages towards the deployment of VLC systems.
