PEAK POWER SUPPRESSING APPARATUS AND PEAK POWER SUPPRESSING METHOD

摘要

A peak power suppressing apparatus capable of improving the reception error rate characteristic of an apparatus on a reception side. In this apparatus, a clipping part (102) clips an input signal, thereby suppressing the peak power of the signal. A subtracting circuit (104) extracts an in-band distortion component of the peak power suppressed signal. A subtracting circuit (111) subtracts the extracted in-band distortion component from the peak power suppressed signal, thereby removing the residual distortion component in the band of the peak power suppressed signal.
