Abstract

fetched live from OpenAlex

High-resolution time-domain ultra-wideband (UWB) channel characterization with CLEAN deconvolution has become increasingly popular. However, due to the extremely wide bandwidth of the pulse, the assumption of negligible pulse distortion no longer holds. In this paper, we first summarize the current works in channel characterization with the CLEAN algorithm. We then show the a priori dependence of CLEAN, and propose a modified multi-template approach to overcome these issues while retaining its high-resolution capability.

Full frame distilled prediction

Teacher imitation

Not 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.
