Abstract: front page image
(EN)Disclosed are a digital signal processing apparatus and a wireless communication system for controlling cell boundary interference using an active antenna system, and a method for controlling cell boundary interference. The system comprises: a digital signal processing apparatus for processing a wireless digital signal, the digital signal processing apparatus being connected to a core system; and a plurality of active antenna systems including an active antenna capable of antenna tilting and beamforming for vertical cell division, the active antenna being physically separated from the digital signal processing apparatus, and a wireless signal processing apparatus for converting and amplifying the digital signal received from the digital signal processing apparatus, transmitting the signal to a terminal through the active antenna, receiving the signal transmitted from the terminal through the active antenna and transmitting the received signal to the digital signal processing apparatus. In the case where interference increases on cell boundaries formed by the active antenna, the digital signal processing apparatus controls the interference on the cell boundaries by forming additional cells on the cell boundaries and dividing the existing cells into a greater number of cells.
(FR)L'invention concerne un appareil de traitement de signal numérique et un système de communication sans fil pour réguler les interférences en bordure de cellule à l'aide d'un système à antenne active, et un procédé de régulation des interférences en bordure de cellule. Le système comporte : un appareil de traitement de signal numérique pour traiter un signal numérique sans fil, l'appareil de traitement de signal numérique étant connecté à un système central ; et plusieurs systèmes à antenne active comportant une antenne active apte à une inclinaison d'antenne et à la formation de faisceau pour la division verticale de cellule, l'antenne active étant physiquement distincte de l'appareil de traitement de signal numérique, et un appareil de traitement de signal sans fil pour convertir et amplifier le signal numérique reçu en provenance de l'appareil de traitement de signal numérique, pour transmettre le signal à un terminal par le biais de l'antenne active, pour recevoir le signal transmis par le terminal par le biais de l'antenne active et pour transmettre le signal reçu à l'appareil de traitement de signal numérique. Dans le cas où les interférences augmentent sur les bordures de cellule formées par l'antenne active, l'appareil de traitement de signal numérique régule les interférences sur les bordures de cellule en formant des cellules supplémentaires sur les bordures de cellule et en divisant les cellules en un plus grand nombre de cellules.
(KO)액티브 안테나 시스템을 이용하여 셀 경계의 간섭을 제어하는 디지털 신호 처리 장치 및 무선 통신 시스템, 그리고 셀 경계 간섭 제어 방법이 개시된다. 이 시스템은 코어 시스템에 연결되어 있으며, 무선 디지털 신호를 처리하는 디지털 신호 처리 장치; 및 상기 디지털 신호 처리 장치와 물리적으로 분리되어 있으며, 수직적 셀 분할을 위한 안테나 틸팅 및 빔포밍이 가능한 액티브 안테나와, 상기 디지털 신호 처리 장치로부터 수신한 디지털 신호를 변환 및 증폭하여 상기 액티브 안테나를 통해 단말로 전송하고, 상기 액티브 안테나를 통해 단말로부터 전송되는 신호를 수신하여 상기 디지털 신호 처리 장치로 전달하는 무선 신호 처리 장치를 포함하는 복수의 액티브 안테나 시스템을 포함한다. 상기 디지털 신호 처리 장치는 상기 액티브 안테나에 의해 형성된 셀간 경계의 간섭이 증가하는 경우 셀의 경계에 추가의 셀을 형성하는 방식으로 이전의 셀을 보다 많은 셀로 분할하여 셀 경계의 간섭을 제어한다.
