Abstract

fetched live from OpenAlex

In this paper, we describe the LINC amplifier concept, and discuss gain and phase mismatch issues that reduce its linearity and degrade its performance. A self-calibration approach for the LINC amplifier is proposed, which is based on minimizing a distortion measure of its output signal in the statistical domain. Computer simulations are carried out to validate the proposed LINC amplifier calibration approach. It is demonstrated that the gain and phase mismatches in the LINC amplifier introduce severe nonlinear distortions to its output signal, which severely degrades the overall system performance, and that the proposed calibration approach accurately determines the gain and phase mismatches, effectively compensates for their effects, and significantly improves the LINC amplifier performance.

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.
