We have been studying a position based system using fluorescent light communication. In this paper we describe how to extract location signals from fluorescent light using digital signal processing. The first step is to calculate the optimal sampling frequency for the signal processing. This is followed by an analysis of the characteristics of the received waveform from the fluorescent light. Based on the analyses of the waveform characteristics we used a decoding method with a sampling frequency of 2MHz at the 1.5m distance between a photo sensor and the fluorescent. Our experiments confirmed the suitability of the method and the error rate of each decoded bit was less than 10^\u003c-4\u003e in all combinations of 8 bit length transmission signal patterns.",
