Abstract

La présente invention permet d'atténuer les effets de guidage décalé (non-line of sight / NLOS) au moyen de la méthode des moindres carrés pondérés (weighted least squares / WLS) dans laquelle les pondérations sont déduites de composantes de trajets multiples (multipath components / MPCs) des signaux reçus. La méthode de pondération peut être employée aussi bien avec des modèles de moindres carrés linéaires et non linéaires, qu'avec différents autres schémas d'atténuation de NLOS tels que des algorithmes à base résiduelle ou des techniques de probabilité maximale.
