To design and evaluate an integrated visible light communication and sensing system that combines multi-band carrierless amplitude and phase modulation with received signal strength trilateration.
Designed a dual-function visible light system utilizing multi-band carrierless amplitude and phase (m-CAP) modulation paired with received signal strength (RSS)-based trilateration.
Incorporated physical light source constraints into the system model, specifically addressing dynamic range limits and modulation bandwidth boundaries.
Evaluated performance through room-scale simulations under varying m-CAP configuration settings to determine general design criteria.
Achieved indoor positioning accuracy with a spatial localization error below 7.17 cm in 90% of tested cases.
Delivered a sustained optical data communication throughput of 32 Mbps alongside illumination levels between 300 and 500 lux across the entire room.
