Abstract
To suppress the peak of the orthogonal multiplex transmission signal which is small in deterioration of the quality of the reception signal by generating the cancellation waveform in synchronization with the timing of the symbol of the transmission signal. There is provided a peak suppressing method that suppresses peaks of an orthogonally multiplexed signal whose orthogonality is ensured in given time units, the method comprising: a first step of detecting the peaks of the orthogonally multiplexed signal; a second step of generating a peak cancellation waveform based on the detected peaks of the orthogonally multiplexed signal; and a third step of removing the peak of the orthogonally multiplexed signal from the orthogonally multiplexed signal using the generated peak cancellation waveform. The second step comprises generating the peak cancellation waveform in said time units of the orthogonally multiplexed signal.
