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…

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…
