Definitions

  • Said first beam former may comprise, for each of said plurality of baseband signals, an analog 2x2 matrix circuit with variable gain factors controlled by a digital control vector generated based on said control signal.
  • the analog 2x2 matrix circuit may comprise a phase rotation matrix defining a required phase shift determined based on the direction of arrival for the radio frequency signals to be received. This provides an expedient implementation of the first beam former.

Abstract

L'invention concerne un récepteur de formation de faisceau qui comprend une pluralité de circuits d'extrémité avant (4, 5, 6, 7, 8) recevant des signaux radiofréquence (RF) à partir d'antennes en réseau (2, 22) et réalisant une conversion descendante de ces derniers en signaux de bande de base analogiques. Une section de réception comprend un premier dispositif de formation de faisceau (11, 12, 13) qui commande la phase et l'amplitude de chaque signal de bande de base analogique individuellement pour obtenir des signaux à décalage de phase analogiques et les combine en un signal de bande de base analogique combiné. Une section de suivi de faisceau comprend des convertisseurs analogique-numérique (35, 36) pour convertir les signaux de bande de base analogiques en signaux de bande de base numériques, et un second dispositif de formation de faisceau. Le second dispositif de formation de faisceau réalise un décalage de phase des signaux de bande de base numériques et combine ces derniers en un signal de bande de base numérique combiné ; et la section de recherche et de suivi peut en outre déterminer, à partir de ce signal, un signal indicatif d'une direction de faisceau et fournir ce dernier comme signal de commande au premier dispositif de formation de faisceau.
