Abstract

Un dispositif de communication sans fil est pourvu d'une capacité intra-dispositif de caractérisation du couplage entre une paire d'antennes. Le dispositif de communication sans fil détermine le couplage par l'intermédiaire d'une mesure de gain de fonctionnement et de mesures de gain d'étalonnage obtenues par l'intermédiaire de ports de test.
