摘要

基于蜂窝网络的移动定位受到越来越多的关注，并开展了一些研究来改进定位算法和技术，使其能够在多种环境(室外/室内)下提供更好的性能。在本文中，我们对UTDOA(上行到达时差)方法感兴趣，该方法可以在可接受的精度范围内确定移动站的位置，并尊重两个区域(室内/室外)的紧急情况。利用MATLAB软件对该方法进行了自适应滤波增强，并采用两种不同的算法来显示所选算法的优点，以及该算法在使用传统电话时的紧急呼叫效率。

Enhanced mobile positioning technique for UMTS users in both outdoor and Indoor environments

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.
