In this paper a novel modulation scheme for visible light communication (VLC) using bright white LEDs (Light Emitting Diode) is introduced. Pulse Dual Slope Modulation (PDSM), an extension of Pulse Slope Modulation (PSM), is presented along with its properties. This modulation scheme attempts to addresses the three major issues in Physical Layer for VLC which are Intra-frame flicker compensation, Interframe flicker compensation and Light dimming.
