Abstract:
An apparatus relates generally to preconditioning an input signal. In this apparatus, a first digital predistortion module and a second digital predistortion module are for receiving the input signal for respectively providing a first predistorted signal and a second predistorted signal. A combiner is for combining the first predistorted signal and the second predistorted signal for providing an output signal. The first digital predistortion module includes a moving mean block for receiving the input signal for providing a moving mean signal. The first digital predistortion module further includes a digital predistorter for receiving the input signal and the moving mean signal for providing the first predistorted signal.
