    篇名/題名:HYBRID TOA/AOA SCHEMES FOR MOBILE LOCATION IN CELLULAR COMMUNICATION
    摘要:Wireless location is to determine the position of the mobile station (MS) in wireless communication
    networks. Due to the measurements with large errors, location schemes give poorer performance in
    non-line-of-sight (NLOS) environments. This paper illustrates methods to integrate all the available
    heterogeneous measurements to achieve more accurate location estimation. The proposed hybrid
    schemes combine time of arrival (TOA) at seven BSs and angle of arrival (AOA) information at the
    serving BS to give location estimation of the MS. The schemes mitigate the NLOS effect simply by the
    weighted sum of the intersections between seven TOA circles and the AOA line without requiring priori
    knowledge of NLOS error statistics. Different NLOS models were used to evaluate the proposed methods.
    It is shown by the simulation results that the proposed methods provide better location accuracy
    comparing with Taylor series algorithm (TSA) and the hybrid lines of position algorithm (HLOP).
