Novel wireless location approach for W-CDMA systems based on multiple sliding correlators

Mobile locationing using time difference of arrival (TDOA) measurements has received considerable attention over the last few years. The classical two-step approach consists of acquiring TDOA measurements followed by a separate computation of the mobile position. This approach suffers from issues such as high outlier probabilities in the TDOA measurement acquisition. The paper presents an approach to estimating the mobile´s position in one single step, improving the performance of the classical approach. Numerical simulations show the gain in terms of outlier probability and positioning accuracy.
