Original Abstract

In modern transmitting devices the digital predistortion technique is widely used for linearizing the power amplifier. There are many algorithms realizing predistortion technique with a different complexity and a stability of results. The several methods are described and compared. The orthogonal polynomials with memory were has proved to be simple enough with suitable results, so it was chosen for modeling a power amplifier and for the predistortion.
