Configure DPD Preprocessor Object
Configure a dpdPreprocessor
object with the PA memory depth set to 4 and the PA nonlinearity degree set to 3.
paMemDepth = 4; paNonlinDeg = 3; paPreprocessor = dpdPreprocessor(paMemDepth,paNonlinDeg);
Generate random QAM-modulated symbols, apply DPD preprocessing, and show the size of the augmented DPD preprocessor input returned.
M = 16; % 16-QAM
x = randi([0 M-1],10e3,1);
qamRefSym = single(qammod(x,M));
paScalingFactor = 40;
paInputFeatures = paPreprocessor(qamRefSym*paScalingFactor);
size(paInputFeatures)
ans = 1×2
10000 16
Show the characteristic information of the DPD preprocessor object.
