Local positioning, particularly in indoor environments, poses challenges that are not faced by global and terrestrial positioning systems. Many a times, it is cost effective to build these localization schemes on the existing wireless local area networks (WLANs). In that direction, a time-of-arrival (TOA) estimation based on the “distorted template”[1], which is obtained by convolving the clean template with the channel estimate, was proposed in our earlier work. In this paper, the scheme is further examined for different channel estimation techniques. Towards the direction of designing a complete system, the differential time difference of arrival (DTDOA) synchronization scheme is analyzed and based on the analysis, guidelines for positioning the access points is also provided.
