Coding for Positive Rate in the Source Model Key Agreement Problem
Amin Gohari, Onur Günlü, Gerhard Kramer
A two-party key agreement problem with public discussion, known as the source model problem, is considered. By relating key agreement to hypothesis testing, a new coding scheme is…
Existence and Continuity of Differential Entropy for a Class of Distributions
Hamid Ghourchian, Amin Gohari, Arash Amini
In this paper, we identify a class of absolutely continuous probability distributions, and show that the differential entropy is uniformly convergent over this space under the metr…
How Compressible are Innovation Processes?
Hamid Ghourchian, Arash Amini, Amin Gohari
The sparsity and compressibility of finite-dimensional signals are of great interest in fields such as compressed sensing. The notion of compressibility is also extended to infinit…
Playing Games with Bounded Entropy
Mehrdad Valizadeh, Amin Gohari
In this paper, we consider zero-sum repeated games in which the maximizer is restricted to strategies requiring no more than a limited amount of randomness. Particularly, we analyz…
On the Capacity of a Class of Signal-Dependent Noise Channels
Hamid Ghourchian, Gholamali Aminian, Amin Gohari +2
In some applications, the variance of additive measurement noise depends on the signal that we aim to measure. For instance, additive Gaussian signal-dependent noise (AGSDN) channe…
