Capacity Bounds and High-SNR Characterization for MIMO-OWC Channels Under Average-Power Constraint
Sufang Yang, Liang Xia, Longguang Li +7
This paper investigates the capacity of multipleinput multiple-output (MIMO) optical wireless communication (OWC) channels under a total average-power constraint. Since different n…
Secrecy Capacity Analysis and Beamforming Optimization for MIMO-VLC Wiretap Channels
Sufang Yang, Longguang Li, Jintao Wang +5
This paper investigates a multiple-input multipleoutput (MIMO) visible light communication (VLC) wiretap channel consisting of a transmitter, a legitimate receiver, and an eavesdro…
Near-Field Channel Estimation for Extremely Large-Scale Terahertz Communications
Songjie Yang, Yizhou Peng, Wanting Lyu +4
Future Terahertz communications exhibit significant potential in accommodating ultra-high-rate services. Employing extremely large-scale array antennas is a key approach to realize…
CRB Minimization for RIS-aided mmWave Integrated Sensing and Communications
Wanting Lyu, Songjie Yang, Yue Xiu +4
In this paper, reconfigurable intelligent surface (RIS) is employed in a millimeter wave (mmWave) integrated sensing and communications (ISAC) system. To alleviate the multi-hop at…
Mutual Information-Based Integrated Sensing and Communications: A WMMSE Framework
Yizhou Peng, Songjie Yang, Wanting Lyu +4
In this letter, a weighted minimum mean square error (WMMSE) empowered integrated sensing and communication (ISAC) system is investigated. One transmitting base station and one rec…
