Abstract

A network-based scheme for location tracking of mobile stations (MSs) in TD-SCDMA system is proposed. Uplink Angle of arrival (AOA) of each MS is estimated by subspace tracking technique. And time of arrival (TOA) in fractional chip resolution is estimated from channel impulse response. From the two arguments, AOA and TOA, the position of a MS can be determined in a polar coordinate system in the coverage of the serving base station. A Kalman filter is used to smooth the position data set and track velocity. Computer simulations show that this location scheme has good performance, especially in rural and suburban area.
