Fisher Information and Support Complexity of Gaussian Mixtures
Luca Barletta, Alex Dytso
We study lower bounds on the Fisher information of Gaussian location mixtures and their applications to estimation problems. First, for a discrete mixing distribution, we derive a…
Fundamental Limits of Dynamic Tracking and Communication: A Stationary Policy Formulation
Mohammadreza Bakhshizadeh Mohajer, Luca Barletta, Alex Dytso +1
We study a dynamic integrated sensing-and-communication problem in which a multi-antenna transmitter communicates with a receiver while simultaneously tracking a moving target gove…
On the Evolution of the Capacity-Achieving Input Support for the Amplitude-Constrained AWGN Channel
Luca Barletta, Alex Dytso
We consider an additive white Gaussian noise channel subject to a peak-amplitude constraint and study how the support of the capacity-achieving input distribution (CAID) evolves as…
The Binomial Channel: On Capacity, Optimal Inputs, and Beta-Binomial Approximation
Antonino Favano, Mohammadamin Baniasadi, Ian Zieder +2
We study the binomial channel with input alphabet and output alphabet . We investigate its capacity and the structure of the capacity-achieving input and outp…
An Improved Lower Bound on Support Size of Capacity-Achieving Inputs for the Binomial Channel: Extended version
Mohammadamin Baniasadi, Luca Barletta, Antonino Favano +1
We study the binomial channel and the structure of its capacity-achieving input and output distributions. It is known that the capacity-achieving input distribution is discrete and…
Sub-Gaussian Concentration and Entropic Normality of the Maximum Likelihood Estimator
Leighton P. Barnes, Alex Dytso
It is well known that, under standard regularity conditions, the maximum likelihood estimator (MLE) satisfies a central limit theorem and converges in distribution to a Gaussian ra…
