MA-Aided Hierarchical Hybrid Beamforming for Multi-User Wideband Beam Squint Mitigation
Cixiao Zhang, Yin Xu, Xinghao Guo +3
In wideband near-field arrays, frequency-dependent array responses cause wavefronts at different frequencies to deviate from that at the center frequency, producing beam squint and…
Preconditioned Conjugate Gradient for MIMO-AFDM System
Jun Zhu, Yin Xu, Dazhi He +3
Affine frequency division multiplexing (AFDM) is a promising chirp-assisted multicarrier waveform for future high mobility communications. A significant challenge in MIMO-AFDM syst…
Channel Estimation for RIS-Assisted mmWave Systems via Diffusion Models
Yang Wang, Yin Xu, Cixiao Zhang +6
Reconfigurable intelligent surface (RIS) has been recognized as a promising technology for next-generation wireless communications. However, the performance of RIS-assisted systems…
ODE-Former for Mobile Channel Prediction: A Novel Learning Structure Leveraging The Physics Continuity
Zhuoran Xiao
Obtaining accurate channel state information (CSI) is crucial and challenging for multiple-input multiple-output (MIMO) wireless communication systems. With the increasing antenna…
Addressing the Curse of Scenario and Task Generalization in AI-6G: A Multi-Modal Paradigm
Tianyu Jiao, Zhuoran Xiao, Yin Xu +9
Existing works on machine learning (ML)-empowered wireless communication primarily focus on monolithic scenarios and single tasks. However, with the blooming growth of communicatio…
