APPARATUS FOR CONTROLLING SIGNAL-TRANSMISSION POWER, MOBILE STATION, METHOD OF CONTROLLING SIGNAL-TRANSMISSION POWER, AND PROGRAM

摘要

The peak-index calculator calculates a peak index as an indication of PAR in accordance with gain factors &bgr; of channels. The coefficient selector includes a lookup table storing therein fitting coefficients X and Y each categorized in accordance with a combination of &bgr;, and selects coefficients X and Y each having a value determined in accordance with a combination of the gain factors &bgr;. The power-reduction calculator calculates a reduction in maximum signal-transmission power in accordance with both the peak index and the selected coefficients X and Y. The TXAGC calculator controls maximum signal-transmission power in accordance with the calculated reduction.
