The position location system using IS-95 CDMA networks

The position location systems have become a hot issue over the past few years in wireless communication. So far, many people have thought of the Global Positioning System (GPS) as position location system. However, we can use the code division multiple access (CDMA) networks of the position location system. Two systems considered for position location system in CDMA networks are direction finding and ranging. We have examined the position location system by considering the direction finding and ranging system and analyzed the performance of both systems. We also propose a position location system for mitigation of the non-line of site (NLOS) propagation error in IS-95 CDMA networks. We show that the proposed position location system improves the performance of the NLOS ranging error mitigation.
