Title (EN) RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD
(FR) SYSTÈME DE RADIOCOMMUNICATION ET PROCÉDÉ DE RADIOCOMMUNICATION
(JA) 無線通信システム及び無線通信方法
Abstract:
(EN) This radio communication system is provided with a radio device which functions as a base station and with a signal processing device. The radio device is provided with: a channel estimation unit which, on the basis of a radio signal transmitted from the terminal device, estimates channel information about a radio transmission line between the radio device and a terminal device; a demodulation unit which, on the basis of the channel information estimated by the channel estimation unit, performs soft-decision demodulation on the radio signal; a decoding unit which decodes log-likelihood ratios obtained by the soft-decision demodulation and outputs the result of error detection codes obtained by decoding; and a transmission control unit which, on the basis of the results of the error detection codes, controls transmission to the signal processing device of data obtained by decoding.
(FR) L'invention concerne un système de communication radio qui est pourvu d'un dispositif radio qui fonctionne comme une station de base et d'un dispositif de traitement de signal. Le dispositif radio est pourvu : d'une unité d'estimation de canal qui, sur la base d'un signal radio émis par le dispositif terminal, estime des informations de canal concernant une ligne de transmission radio entre le dispositif radio et un dispositif terminal ; une unité de démodulation qui, sur la base des informations de canal estimées par l'unité d'estimation de canal, effectue une démodulation de décision pondérée sur le signal radio ; une unité de décodage qui décode des rapports de vraisemblance logarithmique obtenus par la démodulation de décision pondérée et délivre le résultat des codes de détection d'erreur obtenus par décodage ; et une unité de commande de transmission qui, sur la base des résultats des codes de détection d'erreur, commande la transmission au dispositif de traitement de signal de données obtenues par décodage.
(JA) 無線通信システムは、基地局として機能する無線装置と信号処理装置とを備え、無線装置は、端末装置から送信された無線信号に基づいて、無線装置と端末装置との間における無線伝送路のチャネル情報を推定するチャネル推定部と、チャネル推定部により推定されたチャネル情報に基づいて、無線信号に対して軟判定復調を行う復調部と、軟判定復調により得られた対数尤度比を復号し、復号により得られる誤り検出符号の結果を出力する復号部と、誤り検出符号の結果に基づいて、復号により得られるデータの信号処理装置への送信を制御する送信制御部と、を備える。
