Abstract

fetched live from OpenAlex

This paper presents a powerful adaptive based band/RF predistorter, which uses advantageously the concept of digital receiver technology into power amplifier (PA) linearization area. The linearizer performs an instantaneous characterization of the PA using two digital receivers to supply its AM-AM and AM-PM transfer functions. W-CDMA signals applying different stress levels on PA are used to evaluate the performance of the predistorter. The entire system is validated using DSP/RF co-simulation for a typical class AB power amplifier. Results from different cases of standards signals reveal a significant reduction in effective output power back off (OBO).

Full frame distilled prediction

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.
