SISO Decoding of Z4 Linear Kerdock and Preparata Codes
Aleksandar Minja, Vojin Šenk
Some nonlinear codes, such as Kerdock and Preparata codes, can be represented as binary images under the Gray map of linear codes over rings. This paper introduces MAP decoding of…
Convolutional Codes with Optimum Bidirectional Distance Profile
Ivan Stanojević, Vojin Šenk
We define the bidirectional distance profile (BDP) of a convolutional code as the minimum of the distance profiles of the code and its corresponding "reverse" code. We present tabl…
Information-Geometric Equivalence of Transportation Polytopes
Mladen Kovačević, Ivan Stanojević, Vojin Šenk
This paper deals with transportation polytopes in the probability simplex (that is, sets of categorical bivariate probability distributions with prescribed marginals). Information…
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…
On the Hardness of Entropy Minimization and Related Problems
Mladen Kovačević, Ivan Stanojević, Vojin Šenk
We investigate certain optimization problems for Shannon information measures, namely, minimization of joint and conditional entropies , , , and maximizatio…
Some Properties of Rényi Entropy over Countably Infinite Alphabets
Mladen Kovačević, Ivan Stanojević, Vojin Šenk
In this paper we study certain properties of Rényi entropy functionals on the space of probability distributions over . Primarily, continuity and c…
