Abstract

L'invention concerne des appareils d'émission/réception d'un dispositif de mesure de canal radio à large bande mettant en oeuvre plusieurs porteuses. Le dispositif de mesure de canal radio à large bande mettant en oeuvre plusieurs porteuses peut mesurer des caractéristiques du canal radio à un domaine de fréquence. Du fait que le canal radio est mesuré au domaine de fréquences par le dispositif de mesure de canal radio à large bande mettant en oeuvre plusieurs porteuses, les caractéristiques du canal peuvent être mesurées et une fréquence de mesure maximale de Doppler est maintenue simultanément à un niveau prédéterminé, indépendemment de l'augmentation du nombre d'antennes émettrices et réceptrices, dans une configuration MIMO.
