Title (EN) MITIGATING EFFECTS OF MULTIPATH DURING POSITION COMPUTATION
(FR) ATTÉNUATION DES EFFETS DE TRAJETS MULTIPLES PENDANT UN CALCUL DE POSITION
Abstract: front page image
(EN)Estimating an unknown position of a receiver. In some embodiment, trilateration techniques that quantify uncertainty in the estimate of the unknown position are applied. One such technique for estimating a two-dimensional or three-dimensional position of a receiver uses an L-l norm computation instead of an L-2 norm computation.
(FR)L'invention concerne l'estimation d'une position inconnue d'un récepteur. Dans certains mode de réalisation, des techniques de trilatération qui quantifient une incertitude dans l'estimation de la position inconnue sont appliquées. Une de ces techniques pour estimer une position en deux dimensions ou en trois dimensions d'un récepteur utilise un calcul de norme L-I au lieu d'un calcul de norme L-2.
