Abstract
In order to improve spectrum efficiency of communication system,a novel time-frequency overlapped hybrid division multiplexing system was researched. A rapid detection algorithm based on Gabor transform and an improved detection algorithm using error back propagation method was proposed. The simulation results show that the proposed rapid detection algorithm obtains significant increase in detection speed at the expense of some performance compared with maximum likelihood sequence estimation algorithm,and that the improved detection algorithm is a good compromise between system performance and detection speed and its performance is still better than the high level modulation with the same spectrum efficiency at a high signal to noise ratio. This shows that improving the transmission data rate with overlapped signals can achieve greater gains than using high-level QAM modulation with the same spectrum efficiency.

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
