FIELD: physics, communications.
SUBSTANCE: invention concerns communication devices. AM and PM amplifier distortion characteristics are defined by autocalibration method. Amplifier properties can be saved in separate conversion tables (526, 712). Alternatively, amplifier property inversion can be saved in separate conversion tables. Signals to be amplified are described in polar format containing phase component with standard amplitude and amplitude component. Phase component can be pre-distorted by application of PM distortion property inversion to the signal. In the same way, amplitude component pre-distorted by application of AM distortion property inversion to the signal. Pre-distorted phase component can be amplified using amplifier characteristics obtained before. Pre-distorted amplitude component can be used to determine amplifier amplification factor with predetermined characteristics.
EFFECT: increased efficiency by reduction of distortion rate caused by amplifier.
