Device positioning has generally been recognized as an enabling technology for numerous
vehicular applications in intelligent transportation systems (ITS). The downlink time …

BACKGROUND Legal as well as commercial demands are driving a great interest in
developing methods for positioning mobile Sta tions (MS's). While mobile positioning may …

BACKGROUND Mobile station positioning has become increasingly impor tant, not only for
Supporting enhanced emergency calling (eg, E-911 in the United States), but also for …

A signal attenuation difference of arrival (SADOA) scheme is proposed to combine with the
time difference of arrival (TDOA) method for mobile location estimation. On the basis of ratio …

We discuss the performance of a cellular location system based on received signal strength
(RSS) measurements. Each mobile station (MS) collects RSS measurements of the downlink …

This paper studies cooperative user positioning using uplink time-difference-of-arrival
(UTDOA) measurements for 4G Long Term Evolution (LTE) cellular networks. Many …

Enabling the positioning of cellular handsets increases the safety level and at the same time
opens exciting commercial opportunities for operators through providing location-based …

Cellular systems evolved from a dedicated mobile communication system to an almost
omnipresent system with unlimited coverage anywhere and anytime for any device. The …

We investigate the non-line-of-sight (NLOS) propagation identification and correction for
time difference of arrival (TDOA) based mobile user location in wireless communication …

In this paper, location estimation algorithms for cellular communications systems employing
orthogonal frequency division multiplexing (OFDM) are investigated. To determine the …
