    Phase measurements based indoor visible light positioning systems by Zhang, Sheng

    Published 2020
    “…As the GPS signals have severe multi-path effects and strong signal attenuations in indoor buildings, visible light with its line of sight (LOS) property and fewer reflections and diffractions gains advantages in the positioning accuracy over other RF-based techniques.There are several positioning algorithms, the simplest one in structure is the received signal strength (RSS) which has good signal-to-noise ratio (SNR) property, but is not feasible in situations with rotations and intensity disturbance. …”
