Data Fusion for Mobile Terminal Location

AbstmcI-"be location of mobile terminals in cellular networks is an important problem with aPPlifations in resoume allocation, lofation sensitive browsing, and emergency communications. A hey problem in mobile terminal location is the of sight ( ~ 0 s ) propagation, measurement quantization, and measurement noise and also bas a reasanable implementation cost. This paper pro. propagation [Z], [3]. These algorithms are based on the use of non-parametric estimation techniques using survey data taken from the propagation environment. This paper proposes data fusion to exploit the independence of the measurement noise between RSS and TDoA measurements to combine the measurements' resoective estimates of a method that is to p~~~
