Reconfigurable Intelligent Surface aided Massive MIMO Systems with Low-Resolution DACs
Jianxin Dai, Yuanyuan Wang, Cunhua Pan +3
We investigate a reconfigurable intelligent surface (RIS)-aided multi-user massive multiple-input multi-output (MIMO) system where low-resolution digital-analog converters (DACs) a…
On the Secrecy Rate of Spatial Modulation Based Indoor Visible Light Communications
Jin-Yuan Wang, Hong Ge, Min Lin +3
In this paper, we investigate the physical-layer security for a spatial modulation (SM) based indoor visible light communication (VLC) system, which includes multiple transmitters,…
Adaptive Spatial Modulation for Visible Light Communications with an Arbitrary Number of Transmitters
Jin-Yuan Wang, Hong Ge, Jian-Xia Zhu +3
As a power and bandwidth efficient modulation scheme, the optical spatial modulation (SM) technique has recently drawn increased attention in the field of visible light communicati…
Widely-Linear Precoding for Large-Scale MIMO with IQI: Algorithms and Performance Analysis
Wence Zhang, Rodrigo C. de Lamare, Cunhua Pan +4
In this paper we study widely-linear precoding techniques to mitigate in-phase/quadrature-phase (IQ) imbalance (IQI) in the downlink of large-scale multiple-input multiple-output (…
