Title (EN) REFERENCE SYMBOL STRUCTURE FOR DFT SPREAD OFDM SYSTEM
(FR) STRUCTURE DE SYMBOLE DE RÉFÉRENCE POUR UN SYSTÈME OFDM ÉTALÉ PAR TRANSFORMÉE DE FOURIER RAPIDE
(KO) DFT SPREAD OFDM 시스템을 위한 레퍼런스 심볼 구조
Abstract: front page image
(EN)Disclosed are a data transmission device for transmitting a reference OFDM symbol generated through the application of the frequency division multiplexing to a reference symbol and a data symbol, and a data receiving device for estimating a channel by using the reference OFDM symbol. The data transmission device is capable of transmitting the reference OFDM symbol to the data receiving device more frequently without a large increase of a PAPR through the frequency multiplexing of the reference and data symbols. Therefore, the data receiving device is able to estimate the channel exactly.
(FR)L'invention concerne un dispositif de transmission de données pour la transmission d'un symbole OFDM de référence, généré par l'application du multiplexage par répartition en fréquence, à un symbole de référence et un symbole de données. L'invention concerne également un dispositif de réception de données pour l'évaluation d'un canal à l'aide du symbole OFDM de référence. Le dispositif de transmission de données est apte à transmettre le symbole OFDM de référence au dispositif de réception de données plus fréquemment sans grande augmentation d'un rapport valeur de crête sur valeur moyenne (PAPR) par multiplexage en fréquence des symboles de référence et de données. Le dispositif de réception de données est ainsi apte à effectuer une évaluation exacte du canal.
(KO)레퍼런스 심볼과 데이터 심볼을 주파수 분할 다중화하여 생성된 레퍼런스 OFDM 심볼을 전송하는 데이터 전송 장치 및 상기 레퍼런스 ODFM 심볼을 이용하여 채널을 추정하는 데이터 수신 장치가 개시된다. 레퍼런스 심볼과 데이터 심볼이 주파수 다중화되어 PAPR이 크게 증가하지 않으면서도, 데이터 전송 장치가 더 자주 레퍼런스 OFDM 심볼을 데이터 수신 장치로 전송할 수 있으므로, 데이터 수신 장치는 정확하게 채널을 추정할 수 있다.
