FIELD: physics.
SUBSTANCE: invention relates to signal processing in communication means, particularly to digital methods for increasing linearity of an analogue transmission channel. When implementing the method, at the second stage of predistortion input, linear-dynamic signal conversion is performed, which is aimed at alignment of quadrature imbalance of the converter channel.
EFFECT: technical result is higher quality of operation of dual-unit digital system for linearization of analogue radio receiver with quadrature modulator and power amplifier.
