Abstract: A method and an apparatus for reducing a PAPR(Peak to Average Power Ratio) of an orthogonal frequency division multiplexing system are provided to prevent collision with a pilot by shifting the position of a reservation tone to equalize the circulation shift of the pilot. Positions of data and a reservation tone are determined by detecting a pilot position for each symbol according to a frame start and calculating a movement value of a subcarrier not to be overlapped with the position of the searched pilot(610,620,630). An impulse waveform is determined by rotating a phase of a complex value stored in a memory by using the determined movement value(640). The reduction value of a peak to average power ratio of an output signal is calculated by using the phase rotated impulse waveform. The peak to average power ratio of the output signal is reduced to the reduction value of the peak to average power ratio(660).
