Abstract
Recently, interference alignment (IA) has attracted great attention due to its superior performance. However, to achieve IA, users have to bear heavy burdens, such as providing enough dimensions, acquiring global channel statement information and affording high computational complexity, which makes IA difficult to apply in practical networks. Therefore, in this letter, we propose a centralized IA (CIA) scheme, where a relay is employed to off-load the burden of mobile users, i.e., interferences are aligned only by the relay. Furthermore, considering that the receivers still need to zero-force the aligned interference, another scheme called centralized zero-forcing (CZF) is proposed to further reduce the burden of the receivers. Closed-form solutions and feasibility conditions of both schemes are presented. Simulation results are presented to validate the effectiveness of the proposed schemes.

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
