|Abstract:||The achievable positioning precision using two different reference signals in long-term evolution (LTE) systems, namely the secondary synchronization signal (SSS) and the cell-specific reference signal (CRS), is presented. Two receiver architectures are presented: SSS-based and CRS-based. The CRS-based receiver refines the time-of-arrival (TOA) estimate obtained from the SSS signal by estimating the channel frequency response, yielding a more precise TOA estimate. Experimental results of a ground vehicle navigating with each of the presented receivers are given showing a fivefold reduction in the positioning root-mean square error with the CRS-based receiver over the SSS-based receiver.|
