Mutual Coupling and Visibility Effects in 2D Holographic Curvature-Reconfigurable Apertures
Hang Lin, Shu Sun
Holographic multiple-input multiple-output arrays provide high spatial resolution and flexible wavefront control, but curved or conformal deployments jointly introduce curvature, m…
Spectral Approximation and Ergodic-Capacity Convergence of HMIMO Channels under Spatial-Wavenumber Domain Mismatch
Hangsong Yan, Hong Yang, Shu Sun
We establish quantitative results on finite-dimensional spectral approximation and ergodic-capacity convergence for continuous Holographic Multiple-Input Multiple-Output (HMIMO) ch…
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…
Spatial Correlation and Degrees of Freedom in Arched HMIMO Arrays: A Closed-Form Analysis
Liuxun Xue, Shu Sun, Hangsong Yan
This paper presents a closed-form analysis of spatial correlation and degrees of freedom (DoF) for arched holographic multiple-input multiple-output (HMIMO) arrays, which can be vi…
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…
