Low Complexity Selection Cooperation Techniques Using Information Accumulation in Dual-Hop Relaying Networks
Bibliographic record
Abstract
Three low complexity, single-parameter, selection cooperation protocols, called P-n, P-gamma, and P-t, are introduced for dual-hop relaying networks. The protocols are based on information accumulation, and can potentially be implemented using rateless codes. The protocols have low complexity in terms of the relatively small number of signal-to-noise ratio (SNR) measurements, not requiring global channel gain information, not involving simultaneous multiple transmissions, and using a single design parameter. The expected transmission time for the three protocols is analyzed for block fading channels. As a baseline for performance comparison, a rate optimal protocol, called P-o, is proposed. In the single-relay case, all the protocols, if used with their optimized parameter, coincide with P-o. Large SNR approximations to the optimal parameters, which have good accuracy in large SNR regimes, and satisfactory accuracy for smaller values of SNR, are obtained. The dependence of the optimal parameters on the network parameters is numerically studied for Rayleigh fading. The average rate performances of the schemes are compared with other comparable previous relaying schemes through numerical examples. It is observed that the suboptimal schemes exhibit near-optimal rate performances.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
