ABSTRACT

In this chapter, the authors introduce a nonlinear estimation to improve the positioning performance particularly in the vertical direction. A novel concept has been proposed in for integrating visible light communication with 3-D indoor positioning using a single transmitter and multiple tilted optical receivers. The simulation is repeated for 5000 times, then the average availability rate and positioning error at each point in the horizontal plane are obtained. The device is able to estimate its position when all three receivers are able to get access to line-of-sight (LoS) inks from any transmitter. This approach estimates the angle of arrival based on the power differences between different receivers. It is able to estimate the position when all three receivers are able to get access to LoS links from any transmitter. By employing relationships among the received optical power of different detectors, the angle direction line between the receiver and light emitting diode bulb can be obtained.
