Abstract
A predistortion system for correcting a distortion of a distorting component is provided. It comprises a signal generator, adapted to generate a first signal based upon a reference signal, the distorting component, adapted to generate a second signal, based upon the first signal, and an iterative predistortion device, adapted to determine a compensated signal based upon the second signal and the reference signal. The signal generator is adapted to use the compensated signal as reference signal in further iterations after a first iteration. The predistortion system moreover comprises a predistortion calculation device, adapted to determine a predistortion function based upon the reference signal and the first signal. The signal generator is then adapted to generate the first signal based upon the predistortion function for further reference signals.
