Abstract :
Mobile positioning by cellular networks has received growing attention and several researches are carried out to enhance positioning algorithms and techniques that will be able to give better performance at multiple environments (outdoors/indoors). In this paper, we are interested in UTDOA (uplink time difference of arrival) approach to determine the location of a Mobile Station within an acceptable accuracy and respect of emergency cases in both areas (Indoor/Outdoor). The enhancement of this method is performed with adaptive filtering, with MATLAB software, using two different algorithm to show the advantages of the chosen one, and its efficiency in emergency calls even with legacy phones.
