Title (EN) RADIO DEVICE
(FR) DISPOSITIF RADIO
Abstract:
(EN) A radio device (1000) separates the signal from a specific terminal among from the signals from adaptive array antennas (#1 to #4) according to a reception weight vector calculated by a reception weight vector calculator (20). A reception coefficient vector calculator (22) derives an impulse response of a propagation path of the signal from the specific signal. A transmission coefficient vector inferring device (32) predicts the propagation path at the transmission time from the results of the inference by the reception coefficient vector (22). A transmission weight vector calculator (30) controls the antenna directivity at the transmission time according to the results of the prediction by the transmission coefficient vector inferring device (32). In such a way, the degradation of the error rate of the downstream line due to time difference between the upstream and downstream lines can be suppressed.
(FR) L'invention concerne un dispositif radio (1000) séparant le signal provenant d'un terminal spécifique des signaux provenant d'un réseau d'antennes adaptatives (#1 à #4) en fonction d'un vecteur de pondération de réception calculé par un calculateur (20) de vecteurs de pondération de réception. Un calculateur (22) de vecteurs à coefficient de réception déduit du signal spécifique une réponse impulsionnelle d'un chemin de propagation du signal. Un dispositif (32) d'inférence de vecteurs à coefficient d'émission prévoit le chemin de propagation au moment de l'émission à partir des résultats de l'inférence par le vecteur (22) coefficient de réception. Un calculateur (30) de vecteurs de pondération d'émission commande la directivité de l'antenne au moment de l'émission en fonction des résultats de la prédiction par le dispositif (32) d'inférence de vecteurs à coefficient d'émission. Ainsi, la dégradation du taux d'erreur de la ligne aval due à l'écart temporel entre les lignes amont et aval peut être supprimée.
