Abstract
Non-coherent detection and auto-correlation detection are promising techniques for low complexity, low cost and low data rate ultra-wideband communication applications. For both schemes, the integration region of a receiver integrator significantly affects the bit error rate (BER) performance. In this paper, a method of synchronization and estimating the optimal integration region, i.e., the initial point and the length of the integration, is presented. Following a theoretical BER analysis, a data-aided estimation method using the idea of inter-symbol correlation is proposed. It is shown that using noise corrupted received signals, the proposed method is not only practically applicable, but also enhances the performance compared to non-optimal timing methods.

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
