Abstract
In this paper we study the performance of different vehicular wireless broadcast schemes that rely on repetition as a means for providing reliable communications in Rician environment with capture effect. We investigate different patterns for retransmission and show that the one based on Optical Orthogonal Codes (OOC) performs better than others in terms of probability of success and delay. We propose using different numbers of repetitions for providing different Quality of Service (QoS) priority levels and show this method can effectively provide different QoS classes for different types of data without throughput loss. Probability of success and delay are obtained via simulation for three broadcast schemes in the presence of capture effect in Rician fading environment. Furthermore, analytical solutions are compared to simulation for transmission with no capture as a special case.

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
