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.
