Abstract
An efficient digital Volterra predistorter is presented to compensate for nonlinear distortion with memory induced by a broadband RF high power amplifier. The proposed approach is based on mixed-domain Volterra system estimation and optimal pth-order inverse theory. Simulation results show that higher performance and lower computational complexity are achieved compared to conventional predistortion.
