Abstract
Uplink time difference of arrival (UTDOA) mobile station (MS) localization in cellular systems at spatially separated base stations with known locations is proposed. The UTDOA estimation is implemented using a normalized least mean square (NLMS) based adaptive line enhancer (ALE) followed by a cross correlation. More precisely, the use of ALE-pre-filtered cross correlation is proposed in hyperbolic localization to improve the accuracy of TDOA estimation for reducing the uncertainty in localizing the mobile station. Computer simulation results indicate that proposed ALE-UTDOA technique can achieve superior positioning accuracy than conventional cross correlation (CC) based method.
