Meanwhile, a novel data fusion model is studied, in which RSS parameter is brought to enhance redundancy and location precision, then the conclusion is testified by simulation experiment. In the end, a single base location method utilizing TOA, AOA and variance ratio of AOA is studied in cellular environment and EKF is used to track target and estimate velocity, finally the performance of Kalman filter in three conditions is compared by computer simulation.2、In CDMA network, TDOA/AOA location algorithm is applied on single base station location. Single equipment loading GPS and array antenna is adopted to carry out passive positioning, a new TDOA/AOA mathematical model is constructed and EKF algorithm is derived at last.3、A novel single base station algorithm is studied, which makes full use of multipath parameters of TOA, AOA and AOD gotten from MIMO reversible channel estimation means appeared these years to implement TDOA/AOA/AOD hybrid location. Then the corresponding EKF algorithm is derived and these two methods are compared by computer simulation at last.
