摘要： A radio transmission apparatus performs peak suppression processing in the two stages of pre-peak suppression processing and post-peak suppression processing. The gain adjustment processing of transmission power is performed in the two stages of coarse gain adjustment processing, prior to the pre-peak suppression processing, and fine gain adjustment processing prior to the post-peak suppression processing. The fine gain adjustment processing has a smaller adjustment step width than the coarse gain adjustment processing, and can adjust the transmission power in response to a small variation of the transmission power. In the pre-peak suppression processing, a peak suppression value corresponding to the gain set by the coarse gain adjustment processing is set on the basis of each value being preset in a table for each transmission power value. In the post-peak suppression processing, the peak suppression value corresponding to the gain modified by the fine gain adjustment processing is obtained by calculation.

摘要翻译： 无线发送装置在前峰抑制处理和峰值后抑制处理的两个阶段中进行峰值抑制处理。 传输功率的增益调整处理是在前置峰值抑制处理之前的两级粗调增益调整处理和在峰值后抑制处理之前的精细增益调整处理中进行的。 精细增益调整处理具有比粗调增益调整处理更小的调整步长，并且可以响应于发送功率的小的变化来调整发送功率。 在前峰抑制处理中，基于对于每个发送功率值在表中预先设定的每个值来设定与通过粗调增益调整处理设定的增益相对应的峰值抑制值。 在峰值后抑制处理中，通过计算获得与通过微细增益调整处理修改的增益相对应的峰值抑制值。
