摘要

We propose and demonstrate an AC-power-signal-biased light-emitting-diode (LED) modulation. To minimize the signal distortion, the message signal is up-converted to a carrier of 400 KHz and 60 Hz AC-power signal are combined using our developed bias tee circuit. Measurement result shows a bit error rate (BER) below 10 -8 at a transmission distance of 2 m. This technique is energy-efficient and compatible with AC LED, since AC to DC converter is not needed.
