Resum
This article presents a strategy for enhancing efficiency in power amplifiers (PAs) by combining digital predistortion (DPD) linearization and clipping strategies for orthogonal frequency division multiplexing signals in a WiMAX scenario. On the one hand, by reducing the peak-to-average power ratio of multicarrier signals using the well-known clipping technique, it is possible to perform a more efficient PA amplification. On the other hand, nonlinear and linear distortion introduced by the PA op...
