Abstract: In this paper, we study the method of modeling the power amplifier using the Volterra polynomial with a memory effect, which can simulate the main distortions in the model. This is necessary for further research on digital pre-emphasis without the need to use real network elements.

Keywords: linearization, emphasis, power amplifiers.
