Abstract

fetched live from OpenAlex

In this paper, we analyze the performance of cooperative wireless networks with multiple-relays with single-relay selection using limited feed back, exploiting the concepts of Alamouti space-time coding. A two-stage protocol is used with the relay terminals operating in the amplify-and-forward mode (AF). The analysis uses the Rayleigh fading model to reduce the complexity in handling versatile Nakagami fading channels. Taking these effects into account, symbol error probability (SEP) for single relay selection in a multiple-relay environment is derived . The selection is based on the gain of the source-relay (SR) channel and we claim that this is the best achievable SEP for transmission of the Alamouti code using the described protocol, under the given selection criteria. Numerical results are provided to verify the accuracy of the formulation.

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.
