Baseband volterra filters with even-order terms: Theoretical foundation and practical implications |
Abstract | ||
|---|---|---|
The baseband Volterra series is a general approach to model nonlinear passband systems like radio frequency power amplifiers in equivalent baseband. In the present paper, we review the derivation of the baseband Volterra series using a compact vector notation and show that it only includes odd-order terms. After that, we present a new derivation which shows that by assuming modified basis functionals in the passband, one obtains a baseband Volterra series which also includes even-order terms. By simulations, we demonstrate that the inclusion of the proposed even-order basis functionals improves the performance of behavioral modeling and digital predistortion and decreases the condition number of the regression matrix. |
