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…
Deep Learning Based Antenna Selection for Channel Extrapolation in FDD Massive MIMO
Yindi Yang, Shun Zhang, Feifei Gao +3
In massive multiple-input multiple-output (MIMO) systems, the large number of antennas would bring a great challenge for the acquisition of the accurate channel state information,…
Energy Efficient Transmission Based on Grouped Spatial Modulation for upstream DSL Systems
Jiankang Zhang, Chao Xu, Tong Bai +2
The digital Subscriber Line (DSL) remains an important component of heterogeneous networking, especially in historic city-centers, where using optical fibre is less realistic. Rece…
