Abstract
Data transmissions based on Pulse Position Modulation (PPM) and Inverted PPM (IPPM) are considered for the purpose of light dimming in Visible Light Commu-nication (VLC). To support flexible light dimming in which the transmitter need not inform the receiver about which modulation scheme is being used, automatic detection of modulation scheme and data bits is investigated in this work. The probability of bit error is analyzed and verified using simulation experiments. The proposed method can be useful for VLC-based indoor localization where the receiver moves across different locations whose LED lamps operate at different dimming levels.
