A C++ Environment For Modeling Communication Systems
Bibliographic record
Abstract
Design of a low-level communication protocol must take into account several physical phenomena which are irrelevant at a higher level. The correct interpretation of these phenomena is critical to ensure both the protocol’s agreement with its specification and the eficient utilization of the channel bandwidth. We introduce SMURPH-an object oriented simulator for investigating physical communication systems a2 the medium access control level. SMURPH can be viewed as a combination of a protocol specification system with an emulated environment for executing protocol specifications. This environment is realistic in the sense that it reflects the relevant communication phenomena occurring in real physical channels. SMURPH can be used to aid the protocol design process: the designer can evaluate the protocol performance and test the protocol for correctness without resorting to a physical implementation.

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.
