Analytical Statistics of Vortex Beams in a Turbulent Channel for OAM-Multiplexed FSO Communications
Xinyi Chu, Bo Cao, Renzhi Yuan +3
Orbital angular momentum (OAM) multiplexing can increase the capacity of free-space optical (FSO) communications, whereas atmospheric turbulence causes modal crosstalk and irradian…
SCI-DNN: An Optimization Framework for OAM-Multiplexed FSO Communications
Rui Deng, Renzhi Yuan, Xinyi Chu +5
Orbital angular momentum (OAM) multiplexing can increase the capacity of free-space optical (FSO) communications, but its detection performance is strongly affected by impairments…
Quantum-Limited Symbol-Blind Channel Estimation for Coherent State Discrimination
Hongxu Chen, Renzhi Yuan, Haifeng Yao +1
Residual dispersion breaks temporal-mode matching in photon-starved coherent links. For equiprobable -ary PSK coherent states in a known spectral mode, with unknown symbols and…
Channel Modeling of Satellite-to-Underwater Laser Communication Links: An Analytical-Monte Carlo Hybrid Approach
Zhixing Wang, Renzhi Yuan, Haifeng Yao +2
Channel modeling for satellite-to-underwater laser communication (StULC) links remains challenging due to long distances and the diversity of the channel constituents. The StULC ch…
Multi-Stage CD-Kennedy Receiver for QPSK Modulated CV-QKD in Turbulent Channels
Renzhi Yuan, Zhixing Wang, Shouye Miao +4
Continuous variable-quantum key distribution (CV-QKD) protocols attract increasing attentions in recent years because they enjoy high secret key rate (SKR) and good compatibility w…
