Abstract:	In Release 9 of 3GPP standard, a dedicated positioning signal called Positioning Reference Signal (PRS) has been proposed for enhancing the Location Services (LCS). This paper presents the ranging performance of the PRS in long term evolution (LTE) cellular system. It is believed that this positioning method has a potential to work indoors and provide reliable performance. In this work, we review the characteristics of the PRS; build the physical layer simulation platform; implement optimized algorithms for detection, and demonstrate the ranging performance of PRS. Error sources, interference, and antenna diversity gain are considered in this work. The results show promising ranging performance. The sensitivity to fulfill the E911 requirements would be signal-to-noise ratio (SNR) = -15 dB.
