摘要： An apparatus for reducing PAPR (Peack to Average Power Ratio) in an OFDM (Orthogonal Frequency Division Multiplexing) system includes: an IFFT (Inverse Fast Fourier Transform) unit for performing an IFFT on an input data stream modulated using a specific constellation to generate time-domain signals; a time-domain clipping unit for performing a time-domain clipping on the time-domain signals at a clipping level determined by characteristics of the time- domain signals; an FFT (Fast Fourier Transform) unit for performing an FFT on the clipped time-domain signals to generate frequency-domain signals; and a frequency-domain clipping unit for performing a frequency-domain clipping on the frequency-domain signals. The time-domain clipping reduces PAPR in the OFDM system, and the frequency-domain clipping reduces dis¬ tortions generated by the time-domain clipping.
