Abstract
Orthogonal time frequency space (OTFS) modulation can provide a stable signal in a highly dynamic environment with high speed. In this paper, the PAPR characteristics and peak-to-average ratio (PAPR) reduction methods of OTFS signal with superimposed pilot are studied, and a two-stage PAPR reduction scheme combining distributed superimposed pilot and precoding is proposed. Pilot dispersion is used in the first stage, and partial precoding is used in the second stage to optimize PAPR performance. Simulation results show that this method can reduce the PAPR of superimposed pilot OTFS signal. In addition, in order to make OTFS applicable to vehicle communication, the resolution of OTFS is also analyzed.

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
