Abstract :
This paper is focused in the area of digital pre-distortion linearization of power amplifiers. It presents an adaptive system for simulation of digital predistortion algorithm with transmitter imperfection (amplitude imbalance, phase imbalance, DC offset, analog chain delay) compensation methods. These methods are presented and their performance is discussed.
