In this paper, we present an indoor positioning system were trichromatic white LEDs are used as transmitters and an optical processor based on a-SiC:H technology as mobile receiver. The optical processor is realized using a double p-i-n photodetector with two UV light biased gates. The relationship between the optical inputs (transmitted data) and the corresponding digital output levels (received data) is established and decoded.
