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...
