Abstract

"MéTODO E DISPOSITIVO PARA CALIBRAR UM CONJUNTO DE ANTENAS, DISPOSITIVO DE COMUNICAçãO E ESTAçãO BASE DE TELECOMUNICAçãO MóVEL", particularmente para um sistema de telecomunicação móvel CDMA, é calibrado em tempo real pela injeção de um sinal de calibração que é codificado ortogonalmente aos sinais de tráfego de comunicação. Isto permite que seja realizada uma calibração regular e confiável."METHOD AND DEVICE FOR CALIBRATING A SET OF ANTENNAS, COMMUNICATION DEVICE AND MOBILE TELECOMMUNICATION BASE STATION", particularly for a CDMA mobile telecommunication system, is calibrated in real time by injecting a calibration signal that is orthogonally encoded to the signal signals communication traffic. This allows for regular and reliable calibration.
