GCNO: Gramian Chebyshev Neural Operator for Physics-Based Compression of Wireless Channels proposes a variable‑rate compressor that reports only the dominant propagation paths of a wireless channel instead of a full complex‑valued matrix. The method uses the channel’s receive‑transmit structure to locate paths, applies a first‑order Taylor correction for sub‑grid directions, and recovers path strengths via least squares, all trained without explicit path labels. Experiments on three ray‑traced environments show GCNO outperforms neural feedback baselines in reconstruction accuracy for the same payload or achieves the same accuracy with a lower payload, and it generalizes to unseen antenna counts without retraining.
The paper introduces Physics-Unrolled Hybrid Neural Operator (PU‑HNO), a three‑stage cascade that transforms low‑fidelity ray‑tracing outputs and scene priors into high‑fidelity indoor radio maps by sequentially modeling reflection, diffraction, and scattering. It demonstrates that, under conditionally unbiased label noise, the model can learn stable propagation structures and surpass its own training labels. Experiments on varied floorplans show PU‑HNO outperforming image‑to‑image baselines, wireless learning models, and monolithic neural operators in both image quality and wireless deployment metrics.
