Abstract: Apparatus, system and method relates generally to data communication with noise-shaping crest factor reduction using polyphase transformation. In such a method, a composite signal is received by a delay and a waveform generator. The waveform generator is for noise-shaping crest factor reduction using polyphase transformation. The composite signal is delayed by the delay to provide a delayed composite signal. A waveform is generated by the waveform generator from the composite signal. The waveform is output from the waveform generator having clipping noise with respect to bands of corresponding carriers of the composite signal. The waveform is subtracted from the delayed version of the composite signal for peak-to-amplitude power ratio reduction. A reduced peak version of the delayed version of the composite signal delayed is output from the signal combiner.
