Beschreibung
Zusammenfassung:	The present invention provides a weighted centroid localization (WCL) algorithm, which performs a position estimation based on known positions of gateways and measurements on times of arrival (TOA) at the gateways. The algorithm computes a weighted value of the gateway based on a rank of the gateways when the gateways are sorted by TOA of the gateways. Simulations have demonstrated the robustness of the algorithm under different multipath/fading channel conditions and the good position measurement performance thereof. 본 발명은 게이트웨이들의 알려진 위치들 및 게이트웨이에서의 도달 시간(TOA) 측정들에 기초하여 위치 추정을 수행하는 가중 중심 위치 측정(WCL) 알고리즘을 제안한다. 알고리즘은 게이트웨이들이 그들의 TOA에 의해 분류될 때 그들의 랭크에 기초하여 게이트웨이의 가중치를 계산한다. 시뮬레이션들은 상이한 다중 경로/페이딩 채널 조건들 및 그의 양호한 위치 측정 성능하에서 알고리즘의 견고함을 입증한다.
