Affine Frequency Division Multiplexing for Compressed Sensing of Time-Varying Channels
Wissal Benzine, Ali Bemani, Nassar Ksairi +1
This paper addresses compressed sensing of linear time-varying (LTV) wireless propagation links under the assumption of double sparsity i.e., sparsity in both the delay and Doppler…
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…
