Arrival (OTDoA), detta examensarbete undersöker ytterligare prestandaegenskaper hos UTDoA i LTE. Parallellt med 3GPP:s studie för inomhuspositionering, som huvudsakligen baseras på ner-länk OTDoA, studerar denna avhandling den potentiella användningen av UTDoA i LTE med samma typ av överenskomna scenarier och simuleringsparametrar.

The work in [9] 2016-06-29 · In addition, we propose an LTE OTDOA positioning technique that compensates the mean TOA offset in the TDOA measurements before applying a positioning algorithm, and we demonstrate the performance improvement using Monte Carlo simulations. In this paper, we do not include OTDOA errors due to the network synchronization and intercell interference. Detection of the First Component of the Received LTE Signal in the OTDoA Method 1. Introduction.

The study found that the existing positioning, based on Observed Time Difference of Arrival (OTDOA) in LTE does meet the FCC indoor user requirements for horizontal accuracy. Location-based services and emergency call positioning drive the development of positioning in wireless networks. actually located.

OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs. In dense urban and indoor environments, OTDOA can be used to supplement AGPS, provided the user device can detect position reference signals (PRS) from three or more eNBs. actually located.
