Abstract

Due to emerging cellular standards, such as UMTS, TDMA and WLAN, there is more and more need for so-called multi-mode mobile phones, i.e. phones which support not only one air interface but at least two. According to an exemplary embodiment of the present invention, a simplified synchronization of a plurality of time base units in a receiving station, such as a multi-mode mobile phone, is provided, in which the plurality of time base units is synchronized by performing a calibration of one first time base unit only and then using the calibration for synchronizing the other time base units with the calibrated first time base unit. Since the synchronization of the various time base units can be performed by software, the number of hardware components for synchronization may be significantly reduced.
