Abstract
In this letter, we consider the power allocation for a single-carrier (SC)-based secondary user (SU) transmitter (Tx), which transmits concurrently with an SC or multicarrier (MC) primary user (PU) over the same frequency band. A rate maximization problem for the SU system is formulated subject to an SU-Tx power constraint and an explicit rate loss constraint for the PU system. Due to the nonconvexity of the resulting problem, we propose a successive convex approximation approach to solve the problem where in each iteration closed-form solutions are derived for the power allocation variables of the SU-Tx. We further prove that the proposed algorithm is guaranteed to converge to a local optimum of the original nonconvex problem. Simulation results are provided to show the efficacy of the proposed approach.

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
