Abstract
This paper analyzes the effect of non-linear amplifiers in Serial Modulation (SM) systems. It also investigates a modified version of Selected Mapping (SLM) algorithm for serial modulation. The improvement achieved by using this method to reduce Peak to Average Power Ratio (PAPR) and out of band radiation is represented. The results are also compared with SLM for OFDM. It is shown that this method can reduce out of band radiation of SM more effectively than SLM for OFDM for the same power back-off. To achieve more improvement especially for more nonlinear amplifiers, we suggest to use this modified SLM method with predistortion. OFDM; Serial Modulation; PAPR; SLM algorithm

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
