| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This manuscript focuses on a wireless visible-light communication system with an LED-back-lighted sign board. Possibilities of the system are confirmed by experiment. In the experimental system, the transmitter uses frequency shift keying (FSK), which has constant envelope to avoid fluctuation of luminance and can be received without carrier phase synchronization. Since the noise and signal propagation in Electric/Optical/Electric channel are not flat in frequency, we introduce a weighting equalization before the decision circuit of the receiver. Experimental results show that this weighting improves bit error rate (BER) performance and extend distance between the transmitter and the receiver. |
