Abstract

In this paper, an improved time difference of arrival (TDOA) positioning method using pattern matching (PM) is proposed to achieve a high positioning accuracy of mobile station (MS) in CDMA networks where GPS is not satisfactory. Iterative TDOA method is used for its high accuracy and good robustness. Since the performance of iteration method depends highly on the initial estimation, the proposed method uses the location information from PM to estimate initial value. There is no need to change the hardware of MS. PM's results and other data such as received signal value, time delay are measured by using diagnostic monitoring (DM) software in real environment. The results show that proposed method can provide a better accuracy and outperforms a conventional PM algorithm.
