Zero-Error Capacity of a Class of Timing Channels
Mladen Kovačević, Petar Popovski
We analyze the problem of zero-error communication through timing channels that can be interpreted as discrete-time queues with bounded waiting times. The channel model includes th…
Perfect Codes in the Discrete Simplex
Mladen Kovačević, Dejan Vukobratović
We study the problem of existence of (nontrivial) perfect codes in the discrete -simplex $ Δ_{\ell}^n := \left\{ \begin{pmatrix} x_0, \ldots, x_n \end{pmatrix} : x_i \in \math…
On the Entropy of Couplings
Mladen Kovačević, Ivan Stanojević, Vojin Šenk
In this paper, some general properties of Shannon information measures are investigated over sets of probability distributions with restricted marginals. Certain optimization probl…
Multiset Codes for Permutation Channels
Mladen Kovačević, Dejan Vukobratović
This paper introduces the notion of multiset codes as relevant to the problem of reliable information transmission over permutation channels. The motivation for studying permutatio…
