  • decomposing a signal to be amplified into at least a first part and a second part using at least one amplitude threshold, wherein the first part includes a portion of the signal with a lower peak-to-average power ratio than the signal based on the amplitude threshold, and the second part includes a portion of the signal beyond the amplitude threshold;

    amplifying said at least said first part and said second part to produce at least an amplified first part and an amplified second part; and

    combining said at least said amplified first part and said amplified second part to produce an amplified signal.
