Abstract
This paper proposes a simple Peak-to-Average-Power-Ratio (PAPR) mitigation technique for Discrete Multi-Tone (DMT) systems in high-speed wireline applications. The method dynamically adjusts the DC level of each frame to reduce the signal's PAPR when observed over multiple frames. A detailed system-level analysis with post-layout results shows an expected PAPR reduction of 2.3dB, an SNR improvement of 2.0dB, and a 15% increase in data rate, while introducing a negligible 1% increase in transceiver power, silicon area, and link latency. As a result, this paper proposes a practical method to reduce the PAPR while introducing no negative ramifications.

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
