Abstract: front page image
(EN)A head end device in a distributed antenna system according to an aspect of the present invention comprises: a spectrum analysis unit for analyzing frequency spectrums of multiple base station signals and detecting characteristic information of the multiple base station signals; a control unit for generating a control signal for adjusting the power of the multiple base station signals on the basis of the detected characteristic information; and multiple RF units, each of which receives at least one of the multiple base station signals, and adjusts the power of the received base station signal according to the control signal and outputs the base station signal.
(FR)La présente invention concerne, selon un aspect, un dispositif de tête de ligne dans un système d'antennes réparties qui comprend : une unité d'analyse de spectre pour analyser les spectres de fréquence de multiples signaux de station de base et pour détecter des informations de caractéristiques des multiples signaux de station de base ; une unité de commande pour générer un signal de commande pour régler la puissance des multiples signaux de station de base sur la base des informations de caractéristique détectées ; de multiples unités RF, chacune recevant au moins l'un des multiples signaux de station de base et règlant la puissance du signal de station de base reçu selon le signal de commande et émet le signal de station de base.
(KO)본 발명의 일 측면에 따른 분산 안테나 시스템의 헤드엔드 장치는, 복수의 기지국 신호들의 주파수 스펙트럼을 분석하여 상기 복수의 기지국 신호들의 특성 정보를 검출하는 스펙트럼 분석 유닛과, 상기 검출된 특성 정보에 기초하여 상기 복수의 기지국 신호들의 파워를 조절하기 위한 제어 신호를 생성하는 제어 유닛, 및 각각이 상기 복수의 기지국 신호들 중 적어도 하나를 수신하고, 상기 제어 신호에 따라 상기 수신된 기지국 신호의 파워를 조절하여 출력하는 복수의 RF 유닛을 포함한다.
