In this paper, bias and CRB analysis for both proposed line-of-sight (LoS) and conventional radio-signal-strength (RSS) based positioning methods are derived. In contrast to the conventional lognormal based analysis, the derived error models take …
In this paper, bias and Cramer-Rao bound (CRB) analyses for both proposed line of sight (LoS)-based and conventional received signal strength (RSS)-based ranging methods are provided. A minimum bias of LoS-based ranging is derived, which is based on …
This paper presents a novel RSSI based localization scheme that employs an existing cellular network infrastructure to perform trilateration. Traditional localization schemes employ RSSI-based radial distance estimation and trilateration algorithm. …
