Extremely large antenna array (ELAA) system has been emerging as one of the most promising techniques in future 6G communications. With extremely massive antennas and wide bandwidth, wideband ELAA systems suffer from severe spatial wideband effect (SWE), resulting in a focus blur of the transmitted beam, especially whe...

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...

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.
