This article presents a low-complexity and high-accuracy algorithm using message-passing
approach to reduce the computational load of the traditional tracking algorithm for location …

This paper describes a method for location estimation of mobile wireless local area network
(LAN) clients in multistory buildings using the strength of the received signals in a state …

Extended Kalman filter (EKF), which has long been used in the field of GPS positioning, has
recently been used for indoor positioning, introduced extended Kalman filter (EKF) indoor …

Generally, accuracy of GPS (Global Positioning System) is higher than that of cellular
network. But in tall building urban area or indoor, relatively weak GPS signal makes the …

In this paper we present a novel method for improving the mobile location estimation that the
CGI++ technique produces, using a statistical approach. The method produces significant …

Localization systems for indoor areas using the existing wireless local area network (WLAN)
infrastructure have been suggested recently. However, the current systems are not …

Mobile location estimation has attracted much attention in recent years. Location algorithms
for mobile stations (MSs) can generally be categorized into network-and satellite-based …

In this paper, the matrix pencil algorithm is used to recover the time and angle of signal
arrivals from a mobile device to a base station. Signal transmission within a basic BPSK …

This paper proposes an effective method to localize mobile phones in a CDMA environment.
This is to remedy the performance limitation inherent in the traditional localization …

Abstract LBS (Location Based Service) cannot be realized unless we can obtain the user's
current location. Therefore, in order to realize indoor LBS, many researchers have been …
