Grouped Annulus-Modulated Transceiver Is Almost Full DoF-Achieving for RIS-Assisted Symbiotic Radios Over Spatial-Correlated Channels
Ruo-Qi Sun, Jianfeng Shi, Yonggang Zhu +5
This paper considers a RIS-assisted symbiotic communication system, where additional information is conveyed by the passive reconfigurable intelligent surface (RIS). In existing sc…
Geometrically-Shaped Constellation for Visible Light Communications at Short Blocklength
Jia-Ning Guo, Ru-Han Chen, Jian Zhang +3
In this paper, we present a general framework of designing geometrically shaped constellations for short-packet visible light communications with a peak- and an average-intensity c…
Distribution Decomposition and Sum-Capacity Results of Two-User Optical Intensity Multiple Access Channels
Longguang Li, Ru-Han Chen, Jing Zhou
This paper investigates the sum-capacity of two-user optical intensity multiple access channels with per-user peak- or/and average-intensity constraints. By leveraging tools from t…
On the Capacity of MISO Optical Intensity Channels With Per-Antenna Intensity Constraints
Ru-Han Chen, Longguang Li, Jian Zhang +2
This paper investigates the capacity of general multiple-input single-output (MISO) optical intensity channels (OICs) under per-antenna peak- and average-intensity constraints. We…
Capacity Results for Multiple-Input Multiple-Output Optical Wireless Communication With Per-Antenna Intensity Constraints
Ru-Han Chen, Longguang Li, Jia-Ning Guo +3
In this paper, we investigate the capacity of a multiple-input multiple-output (MIMO) optical intensity channel (OIC) under per-antenna peak- and average-intensity constraints. We…
