PURPOSE: A device and a method are provided to reduce the peak-to-average ratio of an input signal without generating emission out of a remarkable band. CONSTITUTION: The clipping critical generation device(10) for generating a clipping critical signal; a peak dividing unit(20) for receiving the input signal and generating the peak signal of the input signal based on the clipping critical signal; a part extreme dividing unit(30) for receiving the peak signal and generating the extreme signal based on the peak signal; a filter(40) for generating a peak elimination signal by filtering the extreme signal; a delay unit(50) for delaying the input signal for a certain time; an adding apparatus(60) for generating the impulse-clipped signal having the reduced P/A ratio and the improved spectrum response.
