Abstract(in English) | Visible light communication systems are suitable to realize secure indoor networks. In this paper, an optical CDMA scheme with EWO signaling and inverted sequences of a generalized MPSC as a signature code is proposed for visible light CDMA systems. Average light intensity and normalized intensity fluctuation of multiplexed signal are investigated by computer simulation. The proposed scheme has low intensity fluctuation and high average light intensity in comparison with the conventional EWO-MPSC scheme. We also implemented a visible light CDMA system with the proposed scheme. This system has some channels on each of which 31.25KHz MIDI data, coded with a generalized MPSC with a length of 64, is transmitted. It is confirmed that the system can correctly decode every MIDI data transmitted simultaneously. |
