Precoded faster-than-Nyquist signaling using optimal power allocation for OTFS
Zekun Hong, Shinya Sugiura, Chao Xu +1
A precoded orthogonal time frequency space (OTFS) modulation scheme relying on faster-than-Nyquist (FTN) transmission over doubly selective fading channels is {proposed}, which enh…
Optical RISs Improve the Secret Key Rate of Free-Space QKD in HAP-to-UAV Scenarios
Phuc V. Trinh, Shinya Sugiura, Chao Xu +1
Large optical reconfigurable intelligent surfaces (ORISs) are proposed for employment on building rooftops to facilitate free-space quantum key distribution (QKD) between highaltit…
Stacked Intelligent Metasurfaces for Holographic MIMO Aided Cell-Free Networks
Qingchao Li, Mohammed El-Hajjar, Chao Xu +3
Large-scale multiple-input and multiple-output (MIMO) systems are capable of achieving high date rate. However, given the high hardware cost and excessive power consumption of mass…
The Road to Near-Capacity CV-QKD Reconciliation: An FEC-Agnostic Design
Xin Liu, Chao Xu, Yasir Noori +2
New near-capacity continuous-variable quantum key distribution (CV-QKD) reconciliation schemes are proposed, where both the authenticated classical channel (ClC) and the quantum ch…
