The Capacity of a Family of Sticky Channels
Mladen Kovačević
We determine the capacity of a family of -ary sticky-insertion channels. Fix and , and let be the unique positive solution of $λ^d = (q-1) (λ^{d-1} + \cdots…
An Information-Theoretic Analog of the Twin Paradox
Mladen Kovačević, Iosif Pinelis, Marios Kountouris
We revisit the familiar scenario involving two parties in relative motion, in which Alice stays at rest while Bob goes on a journey at speed along an arbitrary trajectory and…
Optimal Error-Detecting Codes for General Asymmetric Channels via Sperner Theory
Mladen Kovačević, Dejan Vukobratović
Several communication models that are of relevance in practice are asymmetric in the way they act on the transmitted "objects". Examples include channels in which the amplitudes of…
Asymptotic Behavior and Typicality Properties of Runlength-Limited Sequences
Mladen Kovačević, Dejan Vukobratović
This paper studies properties of binary runlength-limited sequences with additional constraints on their Hamming weight and/or their number of runs of identical symbols. An algebra…
On the Maximum Entropy of a Sum of Independent Discrete Random Variables
Mladen Kovačević
Let be independent random variables taking values in the alphabet , and . The Shepp--Olkin theorem states th…
Second- and Third-Order Asymptotics of the Continuous-Time Poisson Channel
Yuta Sakai, Vincent Y. F. Tan, Mladen Kovačević
The paper derives the optimal second-order coding rate for the continuous-time Poisson channel. We also obtain bounds on the third-order coding rate. This is the first instance of…
