We have proposed a digital signal processing method for signals in a fluorescent light (FL) communication system. In this paper we investigate transmission speeds and sampling frequencies when using FL communication. The first step is to calculate the upper transmission speed and to propose how to reduce sampling frequency. Based on the analyses of their parameters we have used a decoding method with a transmission speed of 19.2kbps, and a sampling frequency of 1MHz, at a distance of 3.0m between a photo sensor and the FL, and we have checked the bit error rate associated with the digital signaling process. Our experiments have confirmed that the error rate of each decoded bit was less than 10^\u003c-6\u003e.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名",
