Analysis of Power Request and Multiple-Site Techniques for Indoor Wireless Visible-Light Communication System Using LED Lights

Expected to serve in the next generation of illumination, LED offers such advantages as high brightness, lower power consumption and long lifetime. The LED lighting system, based on high switching performance, can also be utilized in communication. So it is available that the research is processed in the LED indoor visible-light communication. In this paper, consulting the channel model of indoor infrared communication, first we calculate the power and SNR distribution in the model room according to the indoor illumination standard; then analyze the performance of the system by using the common modulations and the multiple-site technology when multiple users are sharing the channel; at last show the feasibility of the system by the data analysis.
