A New Approach for Mobile Localization in Multipath Scenarios

Abstract

In this paper we consider the localization of a mobile station (MS) in time division multiple access (TDMA) based communication systems. We use joint angle and delay measurements of the emitted signals, impinging on an antenna array at different base stations (BSs). Contrary to previously reported work, our technique takes into account not only the measurement noise, but also multipath propagation and possible BSs reporting only non line of sight (NLOS) measurements. Data are processed using the maximum likelihood (ML) approach based on an implementation of the Expectation Maximization (EM) algorithm. We illustrate the proposed approach using simulated data.

Data fusion for location integrity in vehicle ad hoc networks

“…For example, cellular location estimation and local positioning system [6,1] use infrastructure (base station) or reference device (RFID) to locate a location. But the newly added devices increase the cost of the system.…”
