CORE-CSI: Minimal-Pilot CSI Prediction via Complex One-Step Residual Evolution for Mobile QPSK Links
Channel aging degrades coherent demodulation in mobile links and makes frequent pilot-based CSI updates costly. This paper proposes CORE-CSI, a lightweight, task-specific, world-model-inspired predictor for one-step complex CSI evolution. Rather than directly regressing the next channel state, CORE-CSI predicts a sampl...
