Abstract :
The effectiveness of digital predistortion techniques for improving the linearity of the transmission path of modern communication systems using multistage signals was examined. A comparative analysis of the digital predistorters based on different behavioral inertial models was carried out. The impact of the input signal and its average power on the complexity of the model implementation is studied for a case when a predetermined level of out-of-band emissions is reached.
