Abstract

This letter presents new experimental results on a 2.7-Mb/s organic light emitting diode (OLED) based visible light communications (VLCs) system. We also demonstrate for the first time an online artificial neural network for any VLC system (including inorganics). The major mitigating factors for OLED-VLC systems are the baseline wander phenomenon causing threshold detection to fail and bandwidth limitation caused by low transport mobility, introducing inter-symbol interference into the link and thus the requirement for an equalizer. The online filtering is implemented using the TI TMS320C6713 DSP board and compared with offline results. © 1989-2012 IEEE.
