Estimating Position of Mobile Terminals with Survey Data

Estimating the position of mobile terminals is an important problem for cellular networks. This paper describes low cost methods of locating mobile terminals in urban environments. These methods use data collected during propagation surveys of the network area. It will be shown how the maximum likelihood estimate and minimum mean-square error estimators can be approximated using survey data. Furthermore, the approximate solutions can provide low variance location estimates with low computational cost compared to other methods.
