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…

Signal Detection for Ultra-Massive MIMO: An Information Geometry Approach
Jiyuan Yang, Yan Chen, Xiqi Gao +2
In this paper, we propose an information geometry approach (IGA) for signal detection (SD) in ultra-massive multiple-input multiple-output (MIMO) systems. We formulate the signal d…
