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…
Finite-Support Structure in i.i.d.-Constrained Capacity of Finite-Memory Poisson Channels
Renzhi Yuan, Mugen Peng
Discrete-time Poisson channels with finite intersymbol interference provide a natural model for direct-detection optical links in which multipath memory and signal-dependent shot n…
Turbulent Multiple-Scattering Channel Modeling for Ultraviolet Communications: A Monte-Carlo Integration Approach
Renzhi Yuan, Xinyi Chu, Tao Shan +2
Modeling of multiple-scattering channels in atmospheric turbulence is essential for the performance analysis of long-distance non-line-of-sight (NLOS) ultraviolet (UV) communicatio…
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…
Generalized Kennedy Receivers Enhanced CV-QKD in Turbulent Channels for Endogenous Security of Space-Air-Ground Integrated Network
Shouye Miao, Renzhi Yuan, Bin Cao +3
Endogenous security in next-generation wireless communication systems attracts increasing attentions in recent years. A typical solution to endogenous security problems is the quan…
