Abstract
A radio system and a method for relaying packetized radio signals is disclosed. The radio system and the method provide a calibration of transmit signals. Furthermore the radio system and the method provide a measurement of a transmit power level. The radio system comprises at least one transmit path, a calibration unit, a base band calibration signal generator synchronized to a synchronization unit, at the least one link and a power sensor. A portion of a selected one of coupled transmit signals is forwarded to a power sensor for measuring a power level, wherein the calibration unit is adapted to update a transmit power level of the at least one transmit path in response to the transmit power level of the selected one of the coupled transmit signals.
