<p>The mobile station has a variable gain amplifier and adjusts a gain of the variable gain amplifier in accordance with a level data signal so as to transmit an output transmission signal for each of slots with transmission power control. The mobile station further has a compensation system for the transmission power control with respect to variance of environment surrounding to the mobile station and so on. The compensation system partially extracts the output transmission signal over each slot and carries out a logarithmic wave detection of the extracted transmission signal to produce a resultant signal of the wave detection. Then the compensation system calculates for each slot an average error of the resultant signal of the level data signal and corrects the level data signal with reference to the average error to produce a corrected level data signal as a newly level data signal. When the gain of the variable gain amplifier is adjusted according to this newly level data signal, transmission power control is compensated and the mobile station produces a gain compensated transmission signal as the output transmission signal.</p> |
