Abstract
A distortion compensation device includes: an odd-order distortion compensation unit that compensates an odd-order distortion occurring at first frequencies used for transmitting an amplified signal, the first frequencies including a plurality of frequencies; and an even-order distortion compensation unit that compensates an even-order distortion occurring at second frequencies different from the first frequencies due to the amplification of the signal, the second frequencies including one or more frequencies.

A distortion compensation device comprising:
- an odd-order distortion compensation unit that compensates an odd-order distortion occurring at first frequencies used for transmitting an amplified signal, the first frequencies including a plurality of frequencies;
- and
- an even-order distortion compensation unit that compensates an even-order distortion occurring at second frequencies different from the first frequencies due to the amplification of the signal, the second frequencies including one or more frequencies.
A distortion compensation method comprising:
- first compensating an odd-order distortion occurring at first frequencies used for transmitting an amplified signal, the first frequencies including a plurality of frequencies;
- and
- second compensating an even-order distortion occurring at second frequencies different from the first frequencies due to the amplification of the signal, the second frequencies including one or more frequencies.
