Abstract For an indoor positioning and communication system using Visible Light Communication (VLC), this report

presented a location estimation model and a receiver based on the analysis of the output signals from specially designed fluorescent lights (FL). This location estimation method and newly developed receivers with photo sensors and a fish-eye camera are not only useful for FLC, but also can be used as a reference for application to the next generation LED light with high accuracy. The series of experiments using the tube type FLC system and compact fluorescent down light VLC system suggests that the empirical results, with the location error of less than 10 cm.
