Abstract

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). This paper presents a novel time-of-arrival estimation technique for IEEE 802.11a WLAN system, which provides better accuracy than the traditional correlation-based scheme.
