Novel phase based, cross-correlation position estimation technique
Ian Oppermann, Anette Karlsson, H. Linderback · 2005
The paper presents a novel delay estimation technique used in a positioning and location system. The delay estimation approach uses a novel spread technique which relies on phase detection of crosscorrelation functions. The system uses a transmitted signal which is based on the very common IEEE 802.11b WLAN preamble. Results are presented for a positioning system which utilises the delay estimation technique.
