Abstract
The omnipresence of LEDs for illumination provides unique opportunities for indoor localization. Signals transmitted by the LEDs can be used to determine the position of a person or object within a room with high precision. The requirements of such applications are different from high speed VLC systems. One of the commonly employed methods for VLC-based localization is optical tracking and imaging while the other is based on trilateration/triangulation. However, in both the methods it is critical that the user device is able to recover signals from each luminaire separately. In order to achieve this, a number of processing methods and devices can be chosen, which will be elaborated in this chapter. Practical implications including the required modifications/additions on the illumination infrastructure to enable positioning are also covered.
