Movable Antenna-Enabled Phase Shifting: Performance Analysis and Position Optimization

High-gain analog beamforming in wireless systems conventionally employs analog phase shifters to coherently combine signals. However, this reliance on active hardware components introduces substantial costs, power consumption, and signal insertion losses, all of which increase with the size of the antenna array. This p...

Toward Alias-Free Channel Extrapolation in Upper Mid-Band Systems: A Spatial-Frequency-Temporal Tensor Learning Approach

A tensor-structure-aware axial-attention neural network (TANN), which integrates axis-wise attention with a lightweight multi-scale CNN-based gating module to incorporate support priors for ADD-domain de-aliasing, and yields a unified model that generalizes across pilot configurations without retraining.
