Optimal power control for energy harvesting cognitive radio networks
Bibliographic record
Abstract
Cognitive radio (CR) can be combined with energy harvesting to lift the spectrum efficiency and make use of green energy. The allocated power for the secondary user (SU) needs to have peak power constraints to restrict the interference with the primary user (PU). On the other side, the energy harvesting property of the nodes leads to the causality feature when allocating the harvested energy. In this paper, we apply our recently proposed geometric water-filling with peak power constraints (GWFPP) and recursion machinery to solve the target throughput maximization problem. The proposed algorithm is precisely defined. It provides the exact optimal solution via efficient finite computation. Optimality of the proposed algorithm is strictly proved. Numerical results are presented to illustrate steps and effectiveness of the proposed algorithm, and the exact optimal solutions to the problem. Significant throughput gain can be observed over the well-known primal-dual interior point method (PD-IPM), which only guarantee to generate an ∈ solution to the problem.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
