Summary: | Disclosed are a signal processing method and a node unit of a multi-operating distributed antenna system (DAS). An embodiment of the present invention provides a signal processing method of a multi-operating DAS, which is a method performed by a node unit of a DAS, the signal processing method comprising the steps of: converting each of one or more radio frequency (RF) signals, transmitted from the outside, into a discrete signal; extracting a downlink signal included in the discrete signal; and routing the extracted downlink signal to one or more sub-units constituting the DAS.
L'invention concerne un procédé de traitement de signal et une unité de nœud d'un système d'antennes distribuées (DAS) multi-fonctionnement. Selon un mode de réalisation, la présente invention porte sur un procédé de traitement de signal d'un DAS multi-fonctionnement, qui est un procédé mis en œuvre par une unité de nœud d'un DAS, le procédé de traitement de signal comprenant les étapes consistant à : convertir chaque signal parmi un ou plusieurs signaux radiofréquence (RF), transmis depuis l'extérieur, en un signal discret ; extraire un signal de liaison descendante inclus dans le signal discret ; et router le signal de liaison descendante extrait vers une ou plusieurs sous-unités constituant le DAS.
멀티 오퍼레이팅 DAS의 신호 처리 방법 및 노드 유닛을 개시한다. 본 발명의 일 실시예에 의하면, 분산 안테나 시스템(Distributed Antenna System, DAS)의 노드(node) 유닛에서 수행되는 방법으로서, 외부로부터 전송된 하나 이상의 RF(Radio Frequency)신호 각각을 이산(discrete)신호로 변환하는 단계; 상기 이산신호에 포함된 다운링크신호를 추출하는 단계; 및 상기 추출된 다운링크신호를 상기 DAS를 구성하는 하나 이상의 하위 유닛으로 라우팅(routing)하는 단계를 포함하는 것을 특징으로 하는 멀티 오퍼레이팅(multi operating) DAS의 신호 처리 방법을 제공한다. |
