Abstract

La présente invention concerne un procédé et des dispositifs de mesure de brouillage. Le procédé comprend : l'acquisition, par un dispositif terminal, d'une première période de mesure ; la réalisation, par le dispositif terminal, d'une annulation d'auto-brouillage dans la première période de mesure et la mesure de l'effet obtenu par l'annulation d'auto-brouillage. Dans des modes de réalisation de la présente invention, le dispositif terminal mesure son effet d'annulation durant un processus d'annulation d'auto-brouillage dans la première période de mesure, et ainsi le dispositif terminal mesure l'effet obtenu par l'annulation d'auto-brouillage.
