| Abstract(in English) | Communication using the LED (LED: Light Emitting Diode) which it is being called the next generation illuminationcan can be done by optical intensity modulation. The indoor visible light communication system which the LEDs were used for can use very big transmission electric power by applying high energy efficiency as an illumination to the communication. Therefore, it can think that communication can be done by the reflected light in the location that opto is directly unreachable. But, it can think that the effect of the multi-path due to the reflection such as a wall, a ceiling, stack level is loud in the high speed communication system. Therefore, The effect of the reflection at the wall in the visible light communication system was analyzed in this paper. The characteristics of delay spread against the transition of the receiver field of view angle, SNR and BER were analyzed here. And, the characteristics of the transmit speed and BER at the indoor work plane was evaluated. As for the considerable reflection light in visible light communication system, it knew that adaptation to the high speed communication of about 100Mbps was possible by altering modulation technique. Therefore, visible light communication has big capability, and it can be said as the dominant candidate of the indoor LAN of the future. |
