WebDigital Predistortion (DPD) - Introduction PA is a non-linear device where output y is not simply equal to k * input x. Ex: if x =0.4, output will be 4.7*ej*(4+x) Historically, we only used the PA in its linear region. Ex: 0<= x <=0.18 PA efficiency is very low: ~15% Baseband model of PA: input samples and output samples are complex
WebIt typically takes 3-4 DPD iterations to reach the final performance. Note that machine learning tries to predict the performance of the PA. However, performance is evaluated with a different metric: ACLR. This heuristic works in practice in that the better we can model the PA, the better ACLR we find.
