Abstract
(EN) To provide a communication system wherein it is possible to estimate the transmission path without reducing the transmission capacity in a DSTBC method. A communication system constituting a transmission device (10) and a reception device (20) for communicating in the DSTBC method, wherein: the transmission device (10) space-time encodes one signal having a given signal power as the start symbol of DSTBC and other signals having a signal power of zero, and transmits the encoded signals to the reception device (20); and the reception device (20) independently estimates the transmission path between the transmission antennae of the transmission device and the reception antenna of the reception device by using the space-time encoded start symbol received from the transmission device (10), and decodes a reception signal by means of DSTBC decoding using synchronized detection.
(FR) La présente invention concerne un système de communication permettant d'estimer le trajet de transmission sans réduire la capacité de transmission d'un procédé DSTBC. Selon l'invention, un système de communication est constitué d'un dispositif de transmission (10) et d'un dispositif de réception (20) permettant de communiquer selon le procédé DSTBC. Le dispositif de transmission (10) assure un codage spatio-temporel d'un signal ayant une puissance de signal donnée en tant que symbole de début de DSTBC et d'autres signaux ayant une puissance de signal nulle et transmet les signaux codés au dispositif de réception (20) ; le dispositif de réception (20) estime de manière indépendante le trajet de transmission entre les antennes de transmission du dispositif de transmission et l'antenne de réception du dispositif de réception par utilisation du symbole de début à codage spatio-temporel reçu du dispositif de transmission (10), et décode un signal de réception au moyen d'un décodage DSTBC utilisant une détection synchronisée.
(JA)  DSTBC方式において、伝送容量を低下させることなく伝送路の推定が可能な通信システムを得ること。DSTBC方式で通信を行う送信装置10および受信装置20から構成される通信システムであって、前記送信装置10は、DSTBCのスタートシンボルとして、1つは信号電力を持つ既知信号、残りは信号電力0の既知信号を時空間符号化して前記受信装置20へ送信し、前記受信装置20は、前記送信装置10から受信した時空間符号化された前記スタートシンボルを用いて前記送信装置の送信アンテナと自装置の受信アンテナの各アンテナ間の伝送路を独立に推定し、同期検波を用いたDSTBC復号で受信信号を復号する。
