Abstract
A modified version of the simple block code (SBC) presented by S. Fragicomo et al. (see Electronics Letters, vol.34, no.10, p.953-4, 1998) is proposed to reduce the peak-to-average power ratio (PAPR) of multicarrier systems (such as orthogonal frequency division multiplexing). Combined with the sub-block processing technique (see Zhang, Y. et al., IEEE 49th Vehicular Technology Conference, vol.1, p.695-9, 1999), the proposed scheme can effectively reduce the PAPR of multicarrier systems with large frame sizes. For any given code rate, R/spl ges/3/4, the maximum PAPR reduction that could be achieved by this kind of coding scheme is also derived. A binary phase-shift-keying (BPSK) multicarrier system model is assumed to compare with some well-known results.

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
