downlink oTdoA is a handset-based method, where the as for LTE OTDOA method, a new physical signal- position reference signal (PRS ) [7] dedicated for positioning is introduced to enhance positioning. Because of scalable measurement bandwidth in long term evolution (LTE), the performance of reference signal time difference (RSTD) suffers from small Special reference signals called PRS (Positioning Reference Signal) were designed for the LTE OTDoA method. These signals are placed at a radio resource The OTDOA technology is based on measurement of reference signal time difference (RSTD) from different base stations. The location of a UE can be obtained 13 Aug 2015 In this paper we investigate the positioning accuracy of user equipment (UE) with observed time difference of arrival (OTDoA) technique in Maximum likelihood TOA and OTDOA estimation with first arriving path detection for 3GPP LTE systemŽ.

Improving the Performance of OTDOA based Positioning in

In the OTDOA positioning method, the UE position is estimated based on measurements taken at the UE of downlink radio signals from multiple E-UTRA TPs (possibly including PRS-only E-UTRA TPs from a PRS-based TBS), along with knowledge of the geographical coordinates of the measured TPs and their The accuracy of the observed time difference of arrival (OTDOA) in the long-term evolution (LTE) systems depends on the accuracy of the time of arrival (TOA) measurements, which are often corrupted by various errors caused by non-light-of-sight propagation, multipath interference, noise, and path detection techniques. Furthermore, signal bandwidth, channel condition, distance from the evolved arrival (OTDOA) is a positioning technique introduced in Release 9 of the 3GPP LTE speciﬁcation. In OTDOA technique, the User Equipment (UE) measures the time difference of signals between several eNodeBs (base stations in LTE) and uses a trilateration algorithm to ﬁnd its location.

Baseline performance based on 3GPP 3D MIMO 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. 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.
