Impact of Transceiver on the Multipath Indoor VLC Positioning System

In the present paper, the impact of transceiver configuration has been analyzed for the positioning error in indoor visible light communication system using the received signal strength (RSS) technique. The analysis has been done with four Light Emitting Diodes (LEDs) through Line-of-Sight (LoS) as well as LoS plus first reflection (L-R1) signals. Three different cases have been considered with adjacent separation between each LEDs as 2.5m, 2.00m and 1.5m. The result shows that when the separation between adjacent LEDs is decreased then average received signal strength of LoS as well as L-R1 signals increase but it also causes average positioning error to increase.
