Physics-Aware Huber-Log Differential Total Variation for Hybrid-Field Channel Estimation in 6G UM-MIMO Systems

Ultra-massive multiple-input multiple-output (UM-MIMO) has emerged as a key physical-layer technology for 6G wireless networks. However, the coexistence of far-field and near-field propagation components poses significant challenges to accurate and robust channel estimation. Although existing angular-polar dual-diction...
