Task-guided line-of-sight power-ratio calibration for bias-limited visible light positioning.
Channel impulse response (CIR)-assisted visible light positioning (VLP) improves indoor ranging by separating the line-of-sight (LoS) contribution from multipath-contaminated observations. Practical CIR processing, however, does not provide an ideal LoS measurement: delay-bin aggregation, path-support errors, tap-estim...
