Abstract

fetched live from OpenAlex

A technique for the adaptation of a predistorter is demonstrated. This technique does not provide real-time adaptation but only adjusts to the drifting characteristics of the power amplifier. This technique is based on the ability to sample the out-of-band power and use this scalar quantity to adjust the predistorter coefficients. The predistorter could be implemented in analog form or digitally. Analog predistorters can take the form of cubic predistorters consisting of antiparallel diodes with gain and phase adjustments, intermediate frequency analog polynomials, etc. Digital predistorters using this technique can consist of adjustments to the vector lookup table entries. It is demonstrated that this method requires only a simple adaptation strategy because of the quadratic shape of the surface contour.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Teacher imitation

Not 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.
