Abstract
Wireless backhaul and inter-tower communications networks were previously proposed as key enabling technologies for the next generation digital broadcasting systems, e.g. the Advanced Television Systems Committee (ATSC) 3.0 system. Due to the backward compatibility constraint, conventional symmetrical multi-input multi-output (MIMO) techniques cannot be applied directly in the existing broadcast infrastructure. In this paper, we propose a non-symmetrical approach to integrate MIMO in wireless backhaul and inter-tower communications networks. The proposed schemes maintain the existing broadcast infrastructure, while only adding a low-power RF feeding cable and one or more highly directional antennas to achieve low-cost MIMO implementation for high throughput data distribution and inter-tower networking for the next generation broadcasting systems. The advantages of the proposed system are low deployment cost and full backward compatibility with the ATSC 3.0 broadcast services.

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
