| 摘要 |
The invention relates to a power control method and a power control system used in a transmitter of a radio system comprising an amplifier means (60) and a modulation means (11), which modulates a signal to be transmitted to the radio path. The control system also comprises a control means (90), which forms an amplification control signal (23) used to adjust the transmission power of the signal to be transmitted to the radio path. The control system further comprises a means (17) which forms a reference signal following the changes in the envelope of the modulated signal, and a means (100) which samples the amplified signal in order to form a sample signal. The control means (90) forms a control signal (23), which adjusts the amplification of the amplifier means (60), from the reference signal and the sample signal. |
