Abstract

Des aspects de la présente invention peuvent comprendre, par exemple, la réception, par un élément de réseau d'un système d'antennes distribué, d'un signal de référence et d'un premier signal modulé à une première fréquence porteuse, le premier signal modulé contenant des première données de communication fournies par une station de base et adressées à un dispositif de communication mobile. L'élément convertit le premier signal modulé à la première fréquence porteuse, au premier signal modulé, dans un premier segment spectral sur la base d'un traitement de signal analogique du premier signal modulé et en utilisant le signal de référence pour réduire la distorsion pendant la conversion. L'élément de réseau transmet le premier signal modulé au premier segment spectral, au dispositif de communication mobile, d'une manière sans fil. L'invention concerne également d'autres modes de réalisation.
