PAPR (PEAK-TO-AVERAGE POWER RATIO) DETERMINING DEVICE AND COMMUNICATION DEVICE

摘要

A PAPR determining device includes a detecting unit and a PAPR determining unit. The detecting unit detects a predetermined value's changes, which is a cause of changes in a saturation power of a power amplifier. When the detecting unit detects any change in the predetermined value, the PAPR determining unit determines a PAPR value that corresponds to the saturation power of the power amplifier.
