A calibration system of an array antenna receiving apparatus is used for cellular mobile communication systems. In the array antenna receiving apparatus of the present calibration system, a calibration time determining unit (111) determines an adaptive calibration time based on detection voltages of the total reception power inputted to antenna radio receiving units (104-1 to 104-N). Next, a calibration signal processing unit (112) detects phase/amplitude information of a calibration signal from multiplexing signals outputted from the antenna radio receiving units based on the longest calibration time among the calibration times. User signal processing units (108-1 to 108-M) correct outputs from the antenna radio receiving units based on the phase/amplitude information. Therefore, the deterioration of the reception sensitivity of a user signal to a mobile machine can be prevented and the reduction of the number of users in the cellular system can further be prevented.
Dans un appareil recevant une antenne réseau, une unité de détermination du temps de calibrage (111) détermine un temps de calibrage approprié pour une unité de réception d'une antenne radio (104-1 à 104-N) sur la base de la tension déterminée de la puissance totale reçue par l'unité de réception d'antenne radio. Une unité de traitement de signaux de calibrage (112) détecte les informations de phase/amplitude des signaux de calibrage provenant des multiples signaux émis par les unités de réception d'antenne radio, sur la base du temps de calibrage le plus long. Ensuite, des unités de traitement de signaux d'utilisateur (108-1 à 108-M) corrigent les sorties des unités de réception d'antenne radio sur la base des informations de phase/amplitude.
