Abstract

fetched live from OpenAlex

In previous work we developed the notion of an orthogonal frequency division multiple access (OFDMA) radar: an OFDMA radar is able to execute multiple radar tasks simultaneously. OFDMA encodes information on subcarriers in the frequency domain. By assigning each task a disjoint set of subcarriers, zero-forcing allows for the independent execution of tasks. In this paper we extend this notion further to illustrate another capability of the OFDMA framework, viz., the ability to allocate power differently to different tasks; this degree of freedom in resource allocation can be exploited to enable prioritization amongst the various tasks the radar must execute. In this paper, as proof of concept, we develop the notion of interference-aware power allocation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
