The strong scattering effects of ultraviolet (UV) signals in the atmosphere enables the non-
line-of-sight (NLOS) ability of UV communications, but introduces large time dispersion of …

A photomultiplier tube (PMT) may get saturated if the incident optical power approaches the
saturation threshold for an underwater optical wireless communication (UOWC) system. This …

This paper proposes a method for estimating and detecting optical signals in practical
photon-counting receivers. There are two important aspects of non-perfect photon-counting …

Coherent state quantum communication is attracting extensive attention for its great value in
terrestrial and satellite information networks. This paper proposes a new non-orthogonal …

This paper propose a method for estimating and detecting optical signals in time-gated
single-photon avalanche diode (TG-SPAD) based photon-counting receivers. There are two …

We investigate two-user sum-rate capacity for Poisson channel considering practical photon-
counting receiver, including finite sampling rate and dead time. The sum-rate capacity …
