Optical wireless communication (OWC) using intensity-modulation and direct-detection
(IM/DD) has a channel model which possesses unique features, due to the constraints …

Synchronization channels, such as the well-known deletion channel, are surprisingly harder
to analyze than memoryless channels, and they are a source of many fundamental problems …

Communication theory applied to lightwave channels is ordinarily carried out using the
semiclassical theory of photodetection. Recent development of nonclassical light sources …

The large-inputs asymptotic capacity of a peak-power and average-power limited discrete-
time Poisson channel is derived using a new firm (nonasymptotic) lower bound and an …

The deterministic identification (DI) capacity is developed in multiple settings of channels
with power constraints. A full characterization is established for the DI capacity of the …

Despite being an accepted model for a wide variety of optical channels, few general results
on optimal signalling for discrete-time Poisson (DTP) channels are known. Among the most …

We develop a systematic approach, based on convex programming and real analysis for
obtaining upper bounds on the capacity of the binary deletion channel and, more generally …

We study the maximal achievable rate R*(n,∈) for a given block-length n and block error
probability o over Rayleigh block-fading channels in the noncoherent setting and in the finite …

In the low-energy high-energy-efficiency regime of classical optical communications-
relevant to deep-space optical channels-there is a big gap between reliable communication …

We propose an iterative method for approximating the capacity of classical-quantum
channels with a discrete input alphabet and a finite-dimensional output under additional …
