Dimming control function in light emitting diodes (LED) based visible light communication (VLC) is not only important but challenging too. Many interesting techniques are being investigated for different application scenarios. In this paper, an attempt is made to design a new and effective dimming control mechanism which is adaptive as per environmental condition to address successful data communication in case of infrastructure to vehicular (I2V) or vehicle to vehicle (V2V) or vehicle to infrastructure (V2I) mode of communication in intelligent transportation systems (ITS). We developed pulse dual slope amplitude modulation (PDSAM) to address both flickering and dimming in VLC system and combines the properties of slope and amplitude variation resulting in improved bit error rate (BER) performance. © 2014 IEEE.
