Abstract
The ever increasing demands for mobile Internet access have resulted a significant growth in bandwidth usage. Multi-way relay networks (MWRNs) can address this challenge by improving the system spectral efficiency. In this work, we further improve the spectral efficiency of MWRNs by proposing a novel linear beamforming design, namely partial zero-forcing (PZF), for MWRNs with a multiple-input-multiple-output relay. Compared to zero-forcing (ZF), in PZF, the constraints on the relay beamforming are relaxed such that only partial user-interference, instead of all, is canceled at the relay. After receiving the relay's signal, the users eliminate the remaining interferences through self-interference and successive interference cancellation. By taking such two-stage interference cancellation, PZF better exploits the degrees-of-freedom in MWRNs and achieves higher data rates than ZF.

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
