WLC23-1: Code Shift Keying Modulation For Low-Rate UWB Communications Under Dense Multipath
Bibliographic record
Abstract
Fixed guard times considered for the physical layer of the IEEE 802.15.4a standard (low-rate Wireless Personal Area Networks) cause user asynchronism-dependent collisions that affect the instantaneous bit-error-rate (BER) and packet- error-rate (PER) performances in the presence of simultaneously operating piconets (SOPs). Using code shift keying (CSK), the location of the guard times can be randomized yielding the collision event independent of user asynchronism. In this paper, CSK modulation is adopted for the physical layer of the IEEE 802.15.4a standard with a special code design technique, and it is shown that the proposed implementation of CSK stabilizes the instantaneous BER and PER values. Stabilizing the instantaneous BER and PER values prevents worst-case scenarios, where many packets may be lost due to user asynchronism-dependent collisions, and should be carefully considered for real system implementation.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
