摘要：

Geolocation methods for HIPERLAN/2 OFDM systems were reported recently. This paper continues to study the possibility of overlaying geolocation junctions in 802.11 DSSS wireless LANs. In this paper, a delay measurement-based TDOA measuring method is proposed for 802.11 wireless LANs, which eliminate the requirement of initial synchronization in the conventional methods. The performance of the potential overlaid geolocation systems for DSSS and OFDM wireless LANs are analyzed and compared in terms of symbol synchronization performance.
