Abstract
A signal processing method and power amplifier device are disclosed. The method may include receiving a signal to be transmitted, decomposing an original signal into a plurality of smaller constant-amplitude signals, wherein a vector sum each of the smaller constant-amplitude signals equals the original signal, amplifying the smaller constant-amplitude signals by an amplification factor using a plurality of amplifiers, wherein one or more of the plurality of amplifiers are enabled based on the amplitude of the original signal, combining the amplified smaller constant-amplitude signals into the original signal, the original signal being amplified by the amplification factor, wherein the amplified original signal is transmitted.
