Visible light positioning (VLP) is an emerging localization technique for indoor applications, which utilizes the visible light spectrum to send signals between the optical transmitter (Tx) and the receiver (Rx). In this paper, the recent trend towards the implementation of a single light emitting diode (LED)-based VLP techniques is discussed including the effect of ambient light on the positioning performance. The work establishes a single LED-based VLP scenario, in which the light beacon signal is transmitted from the LED Tx to estimate the location of the user in an indoor environment. The user’s optical Rx is equipped with four photodiodes to receive the free-space light signal in parallel via spatial diversity. The received signal strength indicator-based trilateration scheme is implemented to determine the position of the user. Through simulation, the results demonstrate the 90 th percentile accuracy of 7, 11, and 13 cm for a dark room, a single ambient source, and two ambient sources, respectively. Hence, approximately a 46% reduction in the positioning error is observed for the case of a dark room without the ambient light-inducing noise.
