Peak suppression apparatus

摘要

A peak suppression apparatus includes an acquiring unit that acquires a first signal represented by an amplitude waveform of a multicarrier signal, a generator that generates a second signal represented by a waveform sequentially connecting a plurality of peak points adjacent to one another in the first signal as a peak detection signal for the multicarrier signal, a detector that detects a peak value and a peak timing of the multicarrier signal by using the peak detection signal, and a suppressing unit that suppresses a peak of the multicarrier signal based on the peak value and the peak timing.

1. A peak suppression apparatus comprising:
a memory; and a processor coupled to the memory, wherein the processor executes a process comprising:
acquiring a first signal represented by an amplitude waveform of a multicarrier signal;generating a second signal represented by a waveform sequentially connecting a plurality of peak points adjacent to one another in the first signal based on carrier frequencies and carrier bandwidths of the multicarrier signal;detecting a peak value and a peak timing of the multicarrier signal by using the second signal; andsuppressing a peak of the multicarrier signal based on the peak value and the peak timing, whereinthe generating includes sequentially acquiring maximum amplitude values within a given sample range in the first signal while shifting the given sample range in sequence, generating a third signal represented by a waveform sequentially connecting the acquired maximum amplitude values, and generating the second signal by filtering the third signal based on the carrier frequencies and the carrier bandwidths of the multicarrier signal.
