Abstract :
An OOK based visible light communication system was developed without the use of blue filter, pre-distortion, and equalization techniques in order to decrease size and lower cost. The transmitter consists of a pattern generator, Bias-Tee, a power supply, and an illuminating LED. The receiver is comprised of a PD, a preamplifier, a clock and a data recovery (CDR) unit. A transmission rate of 10Mbps with 0 BER has been achieved without the above techniques and 25Mbps with 0 BER using a blue filter in front of the PD.
