Abstract
This paper addresses the issue of improving distortion compensation in a memoryless digital predistorter. It presents a developed iterative baseband injecting method aimed at overcoming the distortion compensation limit. The concept of the proposed technique is described in the following section. Further section presents experimental verification of the considered PA modelling technique and results of Matlab-ADS co-simulations for demonstrating performances of the proposed predistortion approach.
