摘要：
By using on-off-keying nonreturn-to-zero modulation, a reliable point-to-point visible light communication (VLC) data link between the developed portable VLC transmitter and receiver is established. The VLC structure and principle, the spectral characteristics of white light-emitting diode, and visible detector, and the time- and frequency-domain electro-optical-electro responses, are experimentally studied. Under a definite threshold voltage, the VLC transmission turns out to be band pass feature, and at a communication distance of 0.5 m, the maximum bit rate is up to 4 Mbps. Besides, for dropping the bit error ratio to an acceptable value, a modulation coefficient within the range of 0.68 similar to 1 is preferred, and a suitable bias voltage range is also desired.
