In this paper, we propose a localization algorithm in a visible light communication (VLC) system based on the light intensity. Firstly, by developing a VLC platform, the light intensity can be measured to derive a practical equation, which reveals the relationship between the received signal strength (RSS) and the distance from the transmitter to the receiver. However, the practical additive noise...
In this paper, a three-dimensional (3-D) positioning system using fingerprinting and K-Nearest neighbor is proposed. The implementation of the proposed positioning system based on visible light communication (VLC) is discussed. On-off keying (OOK) modulation, Manchester coding and time division multiplexing (TDM) are utilized to obtain both lossless data and accurate received signal strength indications...
We experimentally demonstrate a visible light communication (VLC) system using pulse amplitude modulation (PAM). A commercially available phosphorised white LED is used as the optical transmitter and a Si photodiode (PD) is used as the optical receiver. The experiment is mainly implemented in an indoor environment which is influenced by the sunlight and fluorescent lamp. In variant conditions, the...
