A RSSI-based indoor visible light positioning approach

We propose a positioning approach based on the monotone signals of the multiple transmitting LEDs and the FFT at the receiver. The position of the receiver can be estimated based on the least-squares (LS) criterion. One advantage of the proposed approach lies in that the receiver does not need the knowledge of the transmission power, in order to estimate the link gain between the transmitter and the receiver. Moreover, the proposed approach does not need perfect synchronization of the received signal from different LEDs, since only signal intensities at different frequency points are needed for the positioning method.
