Abstract
The present invention provides a radio system and a method for relaying radio signals. The radio system comprises at least one transmit path, a digital predistortion unit, a calibration unit and a feedback path. The feedback path is commonly used by the digital predistortion unit and the calibration unit with the present invention. The calibration signal is adapted to update at least one of phase and amplitude changes and the digital predistortion. The present invention further relates to a method for relaying radio signals. The method comprises updating the digital predistortion as well as an updating of the phase and amplitude changes. The updating of the digital predistortion and the updating of the phase and amplitude changes is implemented using a feedback signal. The present invention further relates to a computer program product for the manufacture of the radio system according to the invention. The present invention further relates to a computer program product for the execution of the method according to the present invention.
