Abstract
(EN)
A smart antenna system (100) includes a plurality of antennas (102), a plurality of Transmit - Receive Modules (TRMs) (112) coupled respectively to the plurality of antennas, and a beam steering module (116) coupled to the plurality of TRMs and providing radiation beam steering for the plurality of TRMs. The beam steering module (116) includes a pilot generator (316) for generating a pilot signal and providing it to the TRMs (112) to calibrate a receive (RX) reference plane. The pilot signal is injected at a first location before the receiver section into the RX path, and the pilot signal is sampled at a second location after the receiver section. The TRMs (112) and the beam steering module (116) can also be used to calibrate a transmit (TX) reference plane by sampling output signals from the TRMs. The output signals have a pilot signal component, and are sampled at the first location in the TX path after the transmitter section.

Système d'antennes intelligentes (100) comprenant une pluralité d'antennes (102), une pluralité de modules émetteurs - récepteurs (TRM) (112) couplés respectivement à la pluralité d'antennes, et un module de pilotage de faisceau (116) couplé à la pluralité de TRM et offrant un pilotage du faisceau de radiation pour la pluralité de TRM. Le module de pilotage de faisceau (116) inclut un générateur pilote (316) pour générer un signal pilote et le transmettre aux TRM (112) pour calibrer un plan de référence de réception (RX). Le signal pilote est injecté à un premier emplacement avant la section de réception sur le trajet RX et le signal pilote est échantillonné à un second emplacement après la section de réception. Les TRM (112) et le module de pilotage de faisceau (116) peuvent également être utilisés pour calibrer un plan de référence de transmission (TX) en échantillonnant des signaux de sortie provenant des TRM. Les signaux de sortie ont une composante de signal pilote et sont échantillonnés au premier emplacement sur le trajet TX après la section de transmission.
