Computational and Effective Degrees of Freedom for Spatially Stationary HMIMO Channel Modeling
Hangsong Yan, Hong Yang, Shu Sun
This paper establishes a comprehensive theoretical framework for the continuous-to-discrete modeling of spatially stationary holographic MIMO (HMIMO) channels utilizing the Nystrom…
Robust Multi-Stream Massive MIMO Satellite Systems Based on Statistical CSI
Hangsong Yan, Alexei Ashikhmin, Hong Yang +2
This paper investigates multi-stream downlink precoding for massive multiple-input multiple-output low-Earthorbit satellite (SAT) communication systems. We adopt a delay and Dopple…
Deep Learning-Based Beamforming Design Using Target Beam Patterns
Hongpu Zhang, Shu Sun, Hangsong Yan +1
This paper proposes a deep learning-based beamforming design framework that directly maps a target beam pattern to optimal beamforming vectors across multiple antenna array archite…
