Abstract: front page image
(EN)Disclosed is an apparatus for obtaining symbol synchronization which is robust to a frequency offset in a cell search of a wireless communication system. The symbol synchronization obtaining apparatus may include a sequence generator to generate a base sequence for obtaining the symbol synchronization, a synchronization pattern generator to generate a modified sequence based on the base sequence, and to generate a synchronization pattern by combining the modified sequence and the base sequence, a frequency mapping unit to perform mapping of transmission information to a time area and a frequency area, based on the synchronization pattern, for generating a transmission frame, and a transmitting unit to transmit the transmission frame.
(FR)La présente invention concerne un appareil permettant d'obtenir une synchronisation de symboles résistant à un décalage de fréquence dans une recherche cellulaire d'un système de communication sans fil. L'appareil d'obtention de synchronisation de symboles peut comprendre un générateur de séquence pour générer une séquence de base afin d'obtenir la synchronisation de symboles, un générateur de motifs de synchronisation pour générer une séquence modifiée d'après la séquence de base, et pour générer un motif de synchronisation en combinant la séquence modifiée et la séquence de base, une unité de mise en correspondance de fréquence pour faire correspondre les informations de transmission à une plage de temps et une plage de fréquence, d'après le motif de synchronisation, pour générer une trame de transmission, et une unité de transmission pour transmettre la trame de transmission.
(KO)무선통신시스템의 셀 탐색에서 주파수 오프셋에 강한 심볼 동기 획득 장치가 개시된다. 무선통신시스템의 셀 탐색에서 주파수 오프셋에 강한 심볼 동기 획득 장치는 심볼 동기 획득용 베이스 시퀀스를 생성하는 시퀀스 생성부; 상기 베이스 시퀀스를 기초로 변형 시퀀스를 생성하고, 상기 변형 시퀀스와 상기 베이스 시퀀스를 조합하여 동기 패턴을 생성하는 동기 패턴 생성부; 상기 동기 패턴을 기초로 송신 정보를 시간 및 주파수 영역에 매핑하여 송신 프레임을 생성하는 주파수 매핑부; 및 상기 송신 프레임을 송신하는 송신부를 포함한다.
