Digital Twin Channel-Aided CSI Prediction: A Region-Adaptive Environment-Based Subspace Extraction Approach With Channel Similarity

Low-overhead channel state information (CSI) acquisition is critical for multiple-input multiple-output (MIMO) systems. Digital twin channel (DTC), which reconstructs the 3D physical environment using environmental information, is a promising low-overhead CSI acquisition paradigm. However, most existing works use raw s...

MVLA-GR: A Phase-Free Multipath-Based Geometry Reconstruction Method via Multi-View Likelihood Accumulation for ISAC

Ray-tracing simulations on canonical and complex targets, as well as real-world vehicle measurements at 36 GHz, demonstrate that MVLA-GR can effectively recover target geometry, providing a low-complexity phase-free solution for ISAC.

Electromagnetic World Model for 6G: A Unified Framework for Joint Environment Reconstruction and Channel Prediction

Experimental results show that EMWM outperforms conventional neural network and large language model baselines in both CSI prediction and environment reconstruction, achieving a squared generalized cosine similarity (SGCS) of 0.9699 for CSI prediction while demonstrating robustness across different signal-to-noise rati...
