Abstract

A modulation format of differential pulse amplitude modulation in visible light communication using a single transmitter module composed of multiple semiconductor light-emitting diode (LED) chips is proposed and experimentally demonstrated. Precoded different nonreturn-zero on-off-keying signals were assigned to each LED chip, and linearly overlapped signals were detected by a single photodiode. In this demonstration, pre-equalization and optical filtering were applied to compensate the modulation bandwidth limitation and nonlinearity of the light source. Data rate up to 200 Mbit/s with less than 7.8×10-5 bit error rate was verified by experiment using the proposed modulation method.
