English abstract:
For the firs time, to the best of our knowledge, we experi-mentally demonstrate that multiple-input-multiple-output(MIMO) processing allows using a single photodiode todetect simultaneously a wavelength-division multiplexing(WDM) visible light communications (VLC) signal. Thephotodiode has a triple junction, and when it is illuminatedby a WDM signal, the junctions produce inherently threephotocurrents that are unusable for detecting any of theWDM signals. However, by means of linear MIMO process-ing, we are able to recover the transmitted signals exactly.Bit error rate measurements confim the effectiveness of theproposed solution. This opens a new scenario for practicalWDM-VLC systems.
