Abstract

fetched live from OpenAlex

A fast-low-complexity maximum-likelihood multiuser detector for code division multiple access systems is proposed. It utilizes a best-first branch and bound approach and a constrained memory search. The memory constraint makes the proposed detector realizable, but has negligible performance loss in low signal-to-noise ratio (SNR) and virtually no performance loss in medium-to-high SNR. The results show that the proposed algorithm is much less complex, and that it executes faster than existing maximum likelihood detectors. In addition, the proposed method is suitable for parallel implementation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
