Abstract: front page image
(EN)It is possible to estimate a fading speed of a mobile station and judge whether spatial division multi-connection is appropriate without using a response vector of the mobile station. A radio communication device includes: fading speed estimation unit (30) for detecting a phase change amount of a weight coefficient of an adaptive array antenna and estimating the fading speed of the radio station according to the phase change amount of the weight coefficient; and a communication control unit (12) for controlling to allocate a channel for spatial division multi-connection according to the estimation.
(FR)Il est possible d’estimer une vitesse d’atténuation d’une station mobile et de juger si une multi-connexion à division spatiale est appropriée sans utiliser un vecteur de réponse de la station mobile. L’invention concerne un dispositif de communication radio comprenant : une unité d’estimation de la vitesse d’atténuation (30) pour détecter une quantité de changement de phase d’un coefficient de pondération d’une antenne réseau adaptative et estimer la vitesse d’atténuation de la station radio en fonction de la quantité de changement de phase du coefficient de pondération ; et une unité de commande de communication (12) pour commander l’allocation d’un canal pour une multi-connexion à division spatiale selon l’estimation.
(JA) 本願は、移動局の応答ベクトルを用いることなく、移動局のフェージング速度を推定して空間分割多元接続の適否を判断することを可能とするものである。本願の無線通信装置は、アダプティブアレーアンテナの重み係数の位相変化量を検出し、該重み係数の位相変化量に基づいて無線局のフェージング速度を推定するフェージング速度推定部(30)と、該推定に基づいて、空間分割多元接続用のチャネルを割り当てるように制御する通信制御部(12)とを備える。
