Title (EN) WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD
(FR) DISPOSITIF DE COMMUNICATION SANS FIL ET PROCÉDÉ DE COMMUNICATION SANS FIL
(JA) 無線通信装置および無線通信方法
Abstract: front page image
(EN) This communication device, which relays a received data signal, has: a reception quality measurement unit that calculates propagation characteristics; and a quantization compression encoding unit that, on the basis of a threshold, performs quantization compression of a logarithmic likelihood ratio obtained from a reception signal. The quantization compression encoding unit has a plurality of thresholds used in quantization, and switches between same.
(FR) L'invention concerne un dispositif de communication, qui relaie un signal de données reçu, comprenant : une unité de mesure de qualité de réception qui calcule des caractéristiques de propagation ; et une unité de codage compressif par quantification qui, sur la base d'un seuil, effectue une compression par quantification d'un logarithme du rapport de vraisemblance obtenu à partir d'un signal de réception. L'unité de codage compressif par quantification a une pluralité de seuils utilisés en quantification, et bascule entre eux.
(JA) 受信したデータ信号を中継する通信装置であって、伝搬特性を算出する受信品質測定部と、受信信号より得られた対数尤度比を閾値に基づいて量子化圧縮する量子化圧縮符号化部とを有し、前記量子化圧縮符号化部は、量子化に用いる前記閾値を複数有し、切り替える。
