(54) Title (EN): BASE STATION AND METHOD FOR FACILITATING CALIBRATION OF RADIO OVER FIBER TRANSCEIVERS
(54) Title (FR): STATION DE BASE ET PROCÉDÉ POUR FACILITER L'ÉTALONNAGE D'ÉMETTEURS-RÉCEPTEURS RADIO SUR FIBRE

(57) Abstract:
(EN): The present disclosure provides a base station (400, 800,900). The base station includes a first unit (410) and a second unit (420). The first unit (410) includes a measurement transceiver (480) connected to the second unit (420) and selectively coupled to a first ROF transceiver (453) or a second ROF transceiver (473). The measurement transceiver (480) is configured to: receive from a first ROF receiver (4532) a first analog signal, convert the first analog signal into a first digital signal and transmit the first digital signal to the second unit (420) for calibration of the first ROF transceiver (453), and/or receive from the second unit (420) a second digital reference signal, convert the second digital reference signal into a second analog reference signal and transmit the second analog reference signal to a second ROF transmitter (4731) for transmission to the second unit (420) for calibration of the second ROF transceiver (473).
(FR): La présente invention concerne une station de base (400, 800, 900). La station de base comprend une première unité (410) et une seconde unité (420). La première unité (410) comprend un émetteur-récepteur de mesure (480) connecté à la seconde unité (420) et couplé de manière sélective à un premier émetteur-récepteur radio sur fibre (ROF) (453) ou à un second émetteur-récepteur radio sur fibre (473). L'émetteur-récepteur de mesure (480) est configuré pour : recevoir en provenance d'un premier récepteur ROF (4532) un premier signal analogique, convertir le premier signal analogique en un premier signal numérique et transmettre le premier signal numérique à la seconde unité (420) pour l'étalonnage du premier émetteur-récepteur ROF (453), et/ ou recevoir en provenance de la seconde unité (420) un second signal de référence numérique, convertir le second signal de référence numérique en un second signal de référence analogique et transmettre le second signal de référence analogique à un second émetteur ROF (4731) destiné à être transmis à la seconde unité (420) pour l'étalonnage du second émetteur-récepteur ROF (473).
