<p>A method for compensating signal distortions in multiple transmitting branches (3, 5; 43, 45, 46) entering a composite amplifier (1; 1'). According to the invention the method comprises the steps of: -providing (S1) one or more input signals (x) to the composite amplifier. -observing (S2) an output signal (z) from the composite amplifier (1; 1') for each provided input signal; -deriving (S5) an error in each output signal (z) by comparing the output signal with an ideal output signal, said error being caused by said signal distortions; -deriving (S11) the individual contribution from each transmitting branch (3, 5; 43,45,46) to the error by utilizing a composite amplifier model, said composite amplifier model comprising information about the contribution from each constituent amplifier (23, 25; 103a,103b,103c) to the output signal for each provided input signal: -compensating the signal distortions in the transmitting branches (3, 5; 43,45,46) accordingly.</p> |
