Abstract
According to the structure of antenna arrays and the propagation direction of multipath components,a new multiple input multiple output(MIMO) ultra wideband(UWB) stochastic channel model was proposed from IEEE802.15.3a standard channel model based on parallel ray approximation.The multipath amplitude,phase and arrival time were introduced into the channel model.The extracted channel parameters meet the requirement of UWB channels.From the measurement results,the angle of departure(AOD) and angle of arrival(AOA) can be approximated by Laplace distribution.The relationship between spatial correlation,channel capacity and antenna spacing,angle spread demonstrates that the channel model meets the spatial correlation characteristics in the practical environments.This channel model has great significance for the research of MIMO UWB systems.

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
