Title (EN) A RADIO SYSTEM AND A METHOD FOR RELAYING PACKETIZED RADIO SIGNALS
(FR) SYSTÈME RADIO ET PROCÉDÉ DE RELAIS DE SIGNAUX RADIO EN PAQUETS
Abstract:
(EN) The present invention provides a radio system (1) and a method (800) for relaying packetized radio signals. The radio system (1) comprises at least one transmit path (70-1, 70-2,..., 70-N), a base band calibration signal generator (220B) for generating a base band calibration signal (222B), a digital predistortion unit (300), a calibration unit (200) and a feedback path (400). The feedback path (400) is commonly used by the digital predistortion unit (300) and the calibration unit (200) for feeding back a feedback signal (90F). The feedback signal (90F) is adapted to update at least one of phase and amplitude changes (210-1, 210-2,..., 210-N) and the digital predistortion (310-1, 310-2,..., 310-N). The present invention further relates to a method (800) for relaying packetized radio signals. The method (800) is capable of updating (870) the digital predistortion (310-1, 310-2,..., 310-N) as well as adapted for an updating (880) of the phase and amplitude changes (210-1, 210-2,..., 210-N). The updating (870) of the digital predistortion (310-1, 310-2,..., 310-N) and the updating (880) of the phase and amplitude changes (210-1, 210-2,..., 210-N) is implemented using the feedback signal (90F). The present invention further relates to a computer program product for the manufacture of the radio system (1). The present invention further relates to a computer program product for the execution of the method (800).
(FR) L'invention concerne un système radio (1) et un procédé (800) de relais de signaux radio en paquets. Le système radio (1) comprend au moins un chemin d'émission (70-1, 70-2,..., 70-N), un générateur (220B) de signaux d'étalonnage en bande de base pour produire un signal (222B) d'étalonnage en bande de base, une unité (300) de prédistorsion numérique, une unité (200) d'étalonnage et un chemin de rétroaction (400). Le chemin de rétroaction (400) est utilisé en commun par l'unité (300) de prédistorsion numérique et l'unité d'étalonnage (200) pour produire un signal de rétroaction (90F). Le signal (90F) de rétroaction est conçu pour mettre à jour des changements de phase et d'amplitude (210-1, 210-2,..., 210-N) et/ou la prédistorsion numérique (310-1, 310-2,..., 310-N). LL'invention concerne de plus un procédé (800) de relais de signaux radio en paquets. Le procédé (800) permet de mettre à jour (870) la prédistorsion numérique (310-1, 310-2,..., 310-N) et aussi de mettre à jour (880) les changements de phase et d'amplitude (210-1, 210-2,..., 210-N). La mise à jour (870) de la prédistorsion numérique (310-1, 310-2,..., 310-N) et la mise à jour (880) des changements de phase et d'amplitude (210-1, 210-2,..., 210-N) sont mises en œuvre à l'aide du signal de rétroaction (90F). L'invention concerne de plus un produit de programme informatique utile dans la fabrication du système radio (1). L'invention concerne de plus un produit de programme informatique utile pour mettre en œuvre le procédé (800).
