| Abstract(in English) | We have proposed indoor wireless optical communication systems employing white LEDs. In the previous systems, all LEDs were modulated by the same signal, so entire communication speed was limited by the response speed of LEDs or the speed of an optical sensor. To overcome these limitations, we have proposed parallel transmission approach. A transmit data is divided to multiple packets, and the LEDs in the transmitter is intensity-modulated independently. The receiver image sensor demodulates signals in each pixel in parallel. In this paper, we design an over 1Gbps parallel visible light communications system using white LEDs which is modulated by 5MHz and 2D image sensor whose sampling speed is the same. From numerical analyses, we concluded that this system design could provide office lighting and over 1Gbps data transmission at the same time. |
