Abstract

L'invention concerne une unité réceptrice (1) comportant au moins deux récepteurs de signaux (2a, 2b, 2c) pour la réception de signaux analogiques, un convertisseur analogique-numérique (ADC) pour la conversion des signaux de réception analogiques en signaux de réception numériques ainsi qu'une unité de traitement de signaux (12) pour le traitement des signaux de réception numériques. Ladite unité réceptrice comprend au moins un additionneur (11) à la sortie des récepteurs de signaux (2a, 2b, 2c) permettant l'addition des signaux de réception analogiques, la sortie de cet additionneur (11) étant connectée à l'entrée d'un convertisseur analogique-numérique commun (ADC) et l'unité de traitement de signaux (12) étant conçue pour séparer les signaux de réception additionnés.
