Abstract

In this work, mobile station (MS) localization in cellular systems is considered based on uplink time difference of arrival (UTDOA) of MS signal at spatially separated base stations with known locations is presented. The UTDOA estimation is conducted using 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 UTDOA 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 with range of 67%-75%.
