Abstract

The solution to TDOA(Time Difference of Arrival) equation is obtained by linearizing the equations via a Taylor-series expansion. To achieve high accurate positioning, the first path timing should be estimated correctly. The path search algorithm has been proposed to estimate first path. However, the detection probability of the first path depends on the received power of the pilot symbols. In this paper we propose TDOA mobile terminal positioning with weight control based on received power of pilot symbol in Taylor-series estimation. Computer simulation results indicate the proposed system generally performs better than the conventional system, especially when the transmit power is not high.
