arXiv:2605.22856v1 Announce Type: cross Abstract: Channel foundation models assume access to fully observed channels, an assumption that fails in deployment. We introduce PilotWiMAE, a self-supervised framework whose encoder ingests noisy pilot observations directly and whose attention factorizes along the axis separating temporal from joint space-frequency processing, an inductive bias inspired by the physics of the problem. Pilot input shrinks the observation space by up to two orders of magnitude and also removes the unrealistic assumption of full-CSI availability while incurring lower late
The development of PilotWiMAE emerges as AI model complexity increases and the practical limitations of current channel foundation models in real-world wireless communication deployments become more apparent.
This development is crucial for advancing robust and efficient AI applications in wireless communication, enabling significant improvements by addressing previous unrealistic assumptions about channel information.
The ability to use noisy pilot observations directly and optimize attention for spatial-temporal processing fundamentally alters how AI models learn and operate within wireless communication channels.
