Özet
Indexed keywords Topics of prominence Abstract In visible light positioning (VLP) systems based on the received signal strengtll indicator (RSSI), tile re8ected rays from indoor surfaces distort the RSSI information and increase the positioning error. In this study, the angular diversity receiver (ADR) structure is proposed for RSSI based indoor VLP systems and positioning error is investigated together with photo-detector (PD) selection algorithm. Code division multiple access (CDMA) is used as multiplexing technique for data transfer from LEDs. The complexity of the proposed system is low due to the use of RSSI and CDMA. It has been shown that the proposed strucblre improves the mean squared positioning error performance by 10 em for the elevation angle of 60 degree, and reduces the maximum position error by 75 em at points close to the comers and walls
