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…
Superdirectivity as Boundary Concentration under Spectral Collision
Hong Yang
Array superdirectivity is traditionally derived through singular optimization of densely spaced antenna arrays. In this paper, we show that the phenomenon admits a geometric interp…
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…
Energy-Efficient Flat Precoding for MIMO Systems
Foad Sohrabi, Carl Nuzman, Jinfeng Du +2
This paper addresses the suboptimal energy efficiency of conventional digital precoding schemes in multiple-input multiple-output (MIMO) systems. Through an analysis of the power a…
No Analog Combiner TTD-based Hybrid Precoding for Multi-User Sub-THz Communications
Dang Qua Nguyen, Alexei Ashikhmin, Hong Yang +1
We address the design and optimization of real-world-suitable hybrid precoders for multi-user wideband sub-terahertz (sub-THz) communications. We note that the conventional fully c…
