Summary: | A system and method are described for detecting and controlling the phase difference introduced to radio signals by transmission branches (330,360) of a transmission system in a mobile communication network. Periodically a calibration signal (320) is generated at an input of the transmission branches (330,360) during a phase calibration mode. The phase difference introduced by the two transmission branches is detected by detecting the phase difference between the calibration signal, which has at least partly passed through the first transmission branch and the calibration signal, which has at least partly passed through the second transmission branch. The phase difference between the radio signals is controlled based on the detected phase difference. |
