Positioning system and method with multipath mitigation

The present invention proposed a weighted Centroid Localisation (WCL) algorithm, which does the location estimation based on the known positions of the gateways and the measurements times of arrival (TOA) at the gateways. The algorithm computes the weight of the gateway based on their rank when the...

Beschreibung
Zusammenfassung:	The present invention proposed a weighted Centroid Localisation (WCL) algorithm, which does the location estimation based on the known positions of the gateways and the measurements times of arrival (TOA) at the gateways. The algorithm computes the weight of the gateway based on their rank when the gateways are sorted by their TOA. Simulations have demonstrated the algorithm's robustness under different multipath/fading channel conditions and its good location performance.
