Overview In this webinar, you will learn about digital predistortion (DPD) in modern terrestrial and satellite communications systems. We start by showing how to characterize the response of a power amplifier (PA) according to its nonlinearity order and its memory depth. We then show how ...
In this paper a predistorter linearizer is designed to reduce the memory less and also memory effect in different power amplifier models. The proposed method is based on the joint working principle of RLS filter model (polynomial) which compensate intermodulates and the multi-level system excludes...
