Vector Coded Caching Multiplicatively Boosts MU-MIMO Systems Under Practical Considerations
Hui Zhao, Petros Elia
This work presents a first comprehensive analysis of the impact of vector coded caching (VCC) in multi-user multiple-input multiple-output (MU-MIMO) systems with multiple receive a…
Caching Yields up to 5x Spectral Efficiency in Multi-Beam Satellite Communications
Hui Zhao, Dirk Slock, Petros Elia
This paper examines the integration of vector coded caching (VCC) into multi-beam satellite communications (SATCOM) systems and demonstrates that even limited receiver-side caching…
Matched-filter Precoded Rate Splitting Multiple Access: A Simple and Energy-efficient Design
Hui Zhao, Dirk Slock
We introduce an energy-efficient downlink rate splitting multiple access (RSMA) scheme, employing a simple matched filter (MF) for precoding. We consider a transmitter equipped wit…
Exact SINR Analysis of Matched-filter Precoder
Hui Zhao, Dirk Slock, Petros Elia
This paper answers a fundamental question about the exact distribution of the signal-to-interference-plus-noise ratio (SINR) under matched-filter (MF) precoding. Specifically, we d…
