Abstract: A method of processing a visible light communication (VLC) signal using a single-photon avalanche diode (SPAD) includes detecting photons of a VLC signal at a SPAD detector, counting the photons detected by the SPAD detector to generate a combined VLC signal comprising a data signal and an ambient signal, extracting the ambient signal from the combined VLC signal, subtracting the ambient signal from the combined VLC signal to generate the data signal, and outputting the data signal as a bitstream.
