Abstract
Amplification of signals with fluctuating envelopes inevitably leads
to distortion because of non-linear behavior of the
Power Amplifier (PA). Digital Predistortion can counteract these
non-linear effects. In this paper, a novel Digital Predistortion
architecture is presented which is based on the calculation of
crosscorrelation functions using coarsely quantized signals.
The crosscorrelation functions are transformed to the frequency domain
and the spectra are used to calculate the coefficients of the
predistorter memory polynomial. This method has reduced complexity and
slightly improved average performance in comparison with existing schemes.
