Abstract

fetched live from OpenAlex

We present a distributed algorithm for collaborative uplink transmit beamforming that provides robustness against uncertainties in the channel state information. Our algorithm is derived using the available information about the second-order statistics of the channel and the possibly erroneous channel state. It can be applied to both line-of-sight propagation and flat fading channels. The beamforming coefficients of each terminal are computed locally using the available information about its channel and a single parameter that is broadcasted from the base station to all the cooperating terminals.

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.

Not 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.
