The article considers the features of spectrally effective radio signals and the principles of signal formation by differential quadrature amplitude modulation with a shift of π / 4. A method is proposed for compensating for distortion of radio signals with amplitude-phase modulation in a quadrature driver. A distortion compensation scheme is modeled, and the possibility of its application for non-linear amplification of signals with a variable envelope is considered.
