An Adaptive Acoustic Transceiver Testbed on System-on-Chip for Underwater Communication
Bibliographic record
Abstract
This paper describes a test setup to support the development of a bi-directional acoustic communication link relying on adaptive transceivers. The physical layer relies on the JANUS protocol for discovery of new nodes and assessment of the channel conditions. The transmitter has a bandwidth of 5 kHz at a center frequency of 27.5 kHz, while the receiver relies on broadband hydrophones. The embedded system allows to transmit in diverse underwater scenarios, and the System-on-Chip is programmed to transmit various waveforms including through coded Orthogonal Frequency Division Multiplexing (OFDM). Key elements of the program are described to maintain real-time operation on the embedded systems. At the receiver, the data is sampled at 96 kHz and a 4 Mbps cabled link to a host interface is developed to diagnose the communication link reliability.

How this classification was reachedexpand
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.
