Abstract
This paper proposes a new identification technique of Wiener or Hammerstein models applied to model the behavior of wideband RF transmitters. A dynamic exponential weighted moving average (DEWMA) algorithm was firstly applied to the raw signals sampled at the transmitter input and output to deduce the static AM/AM and AM/PM curves that are attributed to the memoryless nonlinear behavior. These memoryless curves were then utilized to deduce an intermediate set of data used in the identification of the dynamic linear sub-model. To model the frequency response and/or the memory effects, a finite impulse response (FIR) filter topology could be employed. The validation of the modeling approach was carried out using a 60-Watt GaAs FET push pull amplifier operating between 1930 MHz to 1990 MHz, which was applied by a two-carrier WCDMA.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
