<p>A PAPR determining device (10) includes a detecting unit (11) and a PAPR determining unit (12). The detecting unit (11) detects a predetermined value's changes, which is a cause of changes in a saturation power of a power amplifier (20). When the detecting unit (11) detects any change in the predetermined value, the PAPR determining unit (12) determines a PAPR value that corresponds to the saturation power of the power amplifier (20). Specifically, the PAPR determining unit (12) sets, as an initial value, a PAPR value that is determined such that the PAPR value is suitable for a case where the saturation power of the power amplifier (20) is the lowest. Furthermore, the PAPR determining unit (12) searches for the largest PAPR set value by gradually increasing the PAPR set value.</p> |
