摘要
对获取户外位置的需求随着对基于位置的服务(LBS)需求的增加。本文研究的是基于接收信号强度(RSS)的蜂窝移动网络基站指纹定位的问题。首先,我们创建一个移动位置信号空间数据库作为指纹库。然后我们引入一个新的定位方法来提高定位的精度,命名为时空定位方法。此方法同时结合了空间定位方法和时间定位方法的优点。
The expectations for knowing the outdoor position is increasing along with the demand for location based service (LBS). This paper considers the problems of fingerprinting localization in cellular mobile network base on RSS observations. First, we create a mobile location signal space database as radio map. And then we introduce a new loca-lization method called spatial-temporal localization method to improve the localization accuracy. This method combines the advantage of both the spatial localization method and the temporal localization method.
