| Description | Location finding for CDMA subscribers using an antenna may at the base station is studied in this paper. Two methods are con-sidered for radio location that are based on time of arrival (TOA) and angle of arrival (AOA) measurements. For TOA estimates, a maximum likelihood algorithm and a practical structure are pro-posed when an antenna array is available. For AOA estimates, a least-squares (LS) algorithm is used. The LS module is combined with a multiple access interference (MAI) cancellation technique to improve the AOA estimation accuracy in multiuser multipath scenarios. 1. |
