The present invention provides a radio system (1) and a method (800) for relaying packetized radio signals. The radio system (1) comprises at least one transmit path (70-1, 70-2,..., 70-N), a base band calibration signal generator (220B) for generating a base band calibration signal (222B), a digital predistortion unit (300), a calibration unit (200) and a feedback path (400). The feedback path (400) is commonly used by the digital predistortion unit (300) and the calibration unit (200) for feeding back a feedback signal (90F). The feedback signal (90F) is adapted to update at least one of phase and amplitude changes (210-1, 210-2,..., 210-N) and the digital predistortion (310-1, 310-2,..., 310-N). The present invention further relates to a method (800) for relaying packetized radio signals. The method (800) is capable of updating (870) the digital predistortion (310-1, 310-2,..., 310-N) as well as adapted for an updating (880) of the phase and amplitude changes (210-1, 210-2,..., 210-N). The updating (870) of the digital predistortion (310-1, 310-2,..., 310-N) and the updating (880) of the phase and amplitude changes (210-1, 210-2,..., 210-N) is implemented using the feedback signal (90F). The present invention further relates to a computer program product for the manufacture of the radio system (1). The present invention further relates to a computer program product for the execution of the method (800). |
