Bit-Interleaved Coded Modulation With Iterative Decoding in Impulsive Noise
Bibliographic record
Abstract
Power-line communications (PLC) suffers performance degradation due mainly to impulsive noise interference generated by electrical appliances. This paper considers the application of bit-interleaved coded modulation with iterative decoding (BICM-ID) in Class-A impulsive noise environment to improve the spectral efficiency and error performance of PLC. In particular, the optimal soft-output demodulator and its suboptimal version are presented for an additive Class-A noise channel so that iterative demodulation and decoding can be performed at the receiver. The effect of signal mapping on the error performance of BICM-ID systems in impulsive noise is investigated, with both computer simulation and a tight error bound on the asymptotic performance. Extrinsic information transfer chart analysis is carried out to illustrate the convergence properties of different mappings. The superior performance of BICM-ID compared to the orthogonal frequency-division multiplex technique is also clearly demonstrated

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.
