ABSTRACT:
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 and a modulation means, which modulates a signal to be transmitted to the radio path. The control system also comprises a control means, which forms an amplification control signal used to adjust the transmission power of the signal to be transmitted to the radio path. The control system further comprises a means which forms a reference signal following the changes in the envelope of the modulated signal, and a means which samples the amplified signal in order to form a sample signal. The control means forms a control signal, which adjusts the amplification of the amplifier means, from the reference signal and the sample signal.
