A Receiver Array to Reduce the Effects of Misalignment in Magneto-Inductive Communication
Bibliographic record
Abstract
In this paper, a magneto-inductive (MI) communication link is designed to cross the air-water interface for a transmitter that is 20 meters below the surface. Simulations are used to identify the geometry of the coils, as well as an optimal transmit frequency on the order of 1 kHz, constrained on a relatively low transmit current of one A RMS. At this frequency, it is shown that the capacity is equal to 5,820 bps, due to the extremely high SNR, over 50 dB. The performance varies significantly with the distance, because the MI link operates in the near field and the bandwidth is reduced because of the conductivity of seawater. The use of an array is demonstrated to improve the SNR with and without misalignment, and a wideband sensor array is proposed to develop a low-noise link receiver. In fact, a 3-element coil array is proposed, and it is expected that the link will be able to achieve an SNR well above 0 dB for a depth of 20 meters.

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.
