Abstract
In this study, a performance comparison of fibre non‐linearity mitigation is performed in the context of 10 and 20 Gb/s coherent optical orthogonal frequency‐division multiplexing and wavelength division multiplexing (CO‐OFDM‐WDM). The authors compare two regression methods based on the third‐order Volterra series and least mean square algorithm in terms of the bit error rate (BER) for different transmission distances and modulation formats. They also evaluate the BER as a function of the number of OFDM subcarriers for the Volterra‐based non‐linear equaliser (VNLE). In addition, by increasing the order of the VNLE from third‐order to fifth‐order series, a significant increase of performance is obtained for 100 Gb/s CO‐OFDM‐WDM system. Likewise, a comparison study of 16‐QAM 40 Gb/s CO‐OFDM system is performed as a function of Q‐factor for support vector machine, Volterra equaliser and linear equaliser, respectively.

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 it
