Abstract:	Amplification of signals with fluctuating envelopes leads to distortion because of non-linear behavior of the Power Amplifier (PA). Digital Predistortion can counteract these non-linear effects. A crosscorrelation predistorter is a digital predistorter, based on the calculation of crosscorrelation functions. The crosscorrelation functions are transformed to the frequency domain and the spectra are used to control the predistorter. In this paper, the crosscorrelation predistorter is described and the performance is given together with the performance of an existing predistorter, the LS predistorter. The crosscorrelation predistorter outperforms the LS predistorter against lower complexity.
