| 摘要 |
A radio transmission apparatus executing peak suppression processing to an input signal in at least two stages, includes a first peak detector detecting a first peak, a maximum peak among peaks exceeding a first threshold, for a plurality of envelopes included in a predetermined input signal section; a second peak detector detecting a second peak exceeding a second threshold, on the basis of each input signal envelope; a first peak suppression unit suppressing the predetermined input signal section to the limit of a first level based on the first peak; a modulation signal generation unit generating a modulated signal modulated from the input signal suppressed by the first peak suppression unit; and a second peak suppression unit suppressing the second peak to the limit of a second level by each modulated signal envelope based on the first level and the second peak.
