| Abstract(in English) | White LEDs (Light Emitting Diodes) with high luminescence efficiency are developed in recent years, and they are capturing the spotlight. Future electric lights will be comprised of white LEDs. Thus, an indoor wireless optical communication system utilizing white LED lights has been proposed from our laboratory and we have been studying about it. Generally, many LED lights will be installed in our room. Therefore, their optical path difference must be considered. The optical path difference generates an inter-symbol interference (ISI) at a user terminal. In this paper, the influence of an optical path difference has been investigated on the existing optical wireless modulation schemes by some computer simulations from the viewpoint of an RMS delay spread. |
