Information Theory With Kernel Methods [PDF]

open access: yesIEEE Transactions on Information Theory, 2022
We consider the analysis of probability distributions through their associated covariance operators from reproducing kernel Hilbert spaces. We show that the von Neumann entropy and relative entropy of these operators are intimately related to the usual ...

Channel Hardening in Massive MIMO: Model Parameters and Experimental Assessment

open access: yesIEEE Open Journal of the Communications Society, 2020
Reliability is becoming increasingly important for many applications envisioned for future wireless systems. A technology that could improve reliability in these systems is massive MIMO (Multiple-Input Multiple-Output).

Analysis of tree algorithm for collision resolution [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
For the tree algorithm introduced by [Cap79] and [TsMi78] let $L_N$ denote the expected collision resolution time given the collision multiplicity $N$. If $L(z)$ stands for the Poisson transform of $L_N$, then we show that $L_N - L(N) ≃ 1.29·10^-4 \cos ...

CNNPRE: A CNN-Based Protocol Reverse Engineering Method

open access: yesIEEE Access, 2023
Given the growth in computer networks and Internet usage, the traditional network environment has evolved into a more intricate system. Many applications utilize unknown communication protocols, for which the specification documentation is not available.

Information Theory

open access: yesNature, 2019
INFORMATION THEORY rests on the fundamental observation that information and uncertainty are related (Shannon and Weaver, 1949). Intuitively, a code can be used to send information from one agent (the transmitter) to another (the receiver) or a channel ...

Group testing: an information theory perspective [PDF]

open access: yesFoundations and Trends in Communications and Information Theory, 2019
The group testing problem concerns discovering a small number of defective items within a large population by performing tests on pools of items. A test is positive if the pool contains at least one defective, and negative if it contains no defectives ...

Structured channel covariance estimation from limited samples for large antenna arrays

open access: yesEURASIP Journal on Wireless Communications and Networking, 2023
In massive multiuser multiple antenna systems, the knowledge of the users’ channel covariance matrix is crucial for minimum mean square error channel estimation in the uplink and it plays an important role in several multiuser beamforming schemes in the ...
