Abstract
Power amplifier (PA) is widely used in communication systems, however, it has nonlinear characteristic. Digital baseband predistortion is an effective approach to compensate for nonlinear distortion of the PA. Accurate models are of significant importance to study PA nonlinear characteristics and design predistorters. Polynomials have been used extensively for modeling the behavior of the PA or the predistorter (PD). For bandpass signals, attention has been paid mainly to odd-order nonlinear terms. In this paper, we reveal the performance of introducing even-order nonlinear terms in baseband predistorter models. Moreover, we analyze the predistorted spectral characteristics of predistorter models. Theoretical analysis and simulation results show that, when the oversampling rates of source signals are designed properly, it is beneficial to include even-order nonlinear terms in baseband predistorter models.
