An Algorithm for Indoor Photo Diode-Based Visible Light Positioning
Authors: ,
Abstract: In recent years, indoor visible light positioning using white LEDs is getting more attention. An algorithm for indoor photo diode-based visible light positioning is proposed, where the time difference of arrival of the received signal, together with the scale and azimuth angle of the receiver is used to determine the location of the receiver. Hyperbola or straight line equations are established and the crossing point of these equations determines the location of the receiver. In a moderate model room, the performance of the proposed algorithm is demonstrated through simulation, with the positioning accuracy usually in the order of millimeters, suitable for various indoor location-based services.
