Abstract
An improved DPD system includes a predistortion module having at least one predistortion function. The predistortion module is configured to receive and subsequently process a baseband signal. The system also includes a power amplifier configured to receive the processed baseband signal from the predistortion module. The system further includes a model calculator configured to program priorities for predistortion functions so that the processed baseband signal transmitted from the predistortion module corresponds to the transmission power of the power amplifier. The model calculator is further configured to send a trigger signal to indicate when data capture from the power amplifier should begin so as to update the predistortion functions. A trigger module in the system is configured to receive the trigger signal and to initiate data capture from the power amplifier upon receipt of the trigger signal.
