System and method for producing an amplified signal

摘要

A method of producing an amplified signal decomposes a signal into at least a first part and second part using at least one amplitude threshold. 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. The second part includes a portion of the signal beyond the amplitude threshold. At least the first part and the second part are amplified to produce an amplified first part and amplified second part, which are combined to produce an amplified signal.
