We consider a communication system whereby T-seconds time-limited codewords are transmitted over a W-Hz band-limited additive white Gaussian noise channel. In the asymptotic regime as WT→∞, it is known that the maximal achievable rates with such

We consider the independent sum of a given random variable with a Gaussian variable and an infinitely divisible one. We find a novel tight upper bound on the entropy of the sum which still holds when the variable possibly has an infinite second momen

We study the probability distribution of age of information (AoI) in arbitrary networks with memoryless service times. A source node generates packets following a Poisson process, and then the packets are forwarded across the network in such a way th

We study the rates of source coding a T -seconds finite duration piece from a W -Hz band-limited real white Gaussian process with the mean squared error as a distortion measure. First we derive a discrete representation by projecting the signal of in

Recent studies found that many channels are affected by additive noise that is impulsive in nature and is best explained by heavy-tailed symmetric alpha-stable distributions. Dealing with impulsive noise environments comes with an added complexity wi

In this paper we study optimal signaling when using time-limited pulses over band-limited Additive White Gaussian Noise channels. We adopt an information theoretic approach and quantify the achievable rates of such systems. We show that the Nyquist c

Practicalcommunication systems use finite duration pulses. As the time-limited pulses have infinite bandwidth, they lose some of their energy when passed through a band-limited channel and their support in time becomes infinite. We derive the achieva

Time-varying fading channels present a major challenge in the design of wireless communication systems. Adaptive schemes are often employed to adapt the transmission parameters to receiver-based estimates of the quality of the channel. We consider a

We consider the problem of Linear Programming (LP) decoding of binary linear codes. The LP excess lemma was introduced by the first author, B. Ghazi, and R. Urbanke (IEEE Trans. Inf. Th., 2014) as a technique to trade crossover probability for "LP ex

We consider infinitesimal perturbations along symmetric stable variables and define a new information measure. We derive a generalized de Bruijn's identity, prove that the new measure satisfies a data processing inequality and a generalized Fisher in
