Abstract

fetched live from OpenAlex

A method to achieve high data rate transmission in a cognitive radio (CR) system with adaptive use of spectrum is proposed. A periodic power spectral density measurement is taken over the span of the transmission band to identify spectral areas with low jammer and/or interference power. A probabilistic algorithm is then used to define spectral regions, adaptively and pseudorandomly, in which a frequency-hopped spread-spectrum (FHSS) system can operate. Simulation results have shown that schemes incorporating spectrum measurement and adaptive frequency hopping, combined with multiband transmission, exhibit relatively large gains compared to schemes employing multiband transmission only and considerable gain when compared to single carrier FHSS transmission schemes

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.
