Due top emerging cellular standards, such as UMTS, TDMA and WLAN, there is more need for so-called multi-mode mobile phones, i.e. phone which support not only one air interface but at least two. According to an exemplary embodiment of the present invention, a simplified synchronization of 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.
Method of synchronizing a first and a second time base unit in a receiving station, the method comprising the steps of:—performing a calibration of the first time base unit, resulting in a calibrated first time base unit;—using the calibration to synchronize the second time base unit with the calibrated first time base unit.
A communication system for synchronizing a first and a second time base unit, the communication system comprising a transmitting station and a receiving station;
A receiving station for a communication system for synchronizing a first and a second time base unit, wherein the receiving station comprises the first and second time base units;
A software program product for performing a synchronization of a first and a second time base unit, wherein the receiving station comprises the first and second time base units, the software program product performing the steps of:
