ECWT: Performance Analysis of Crosscorrelation Predistorters
Performance Analysis of Crosscorrelation Predistorters Andr´ B.J. Kokkeler e University of Twente, P.O. Box 217, 7500 AE Enschede, The Netherlands, Phone: +31 53 4894291 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 nonlinear effects. A crosscorrelation predis
