On maximum distance separable and completely regular codes
Joaquim Borges, Josep Rifà, Victor Zinoviev
We investigate when a maximum distance separable () code over is also completely regular (). For lengths and we provide a complete classification of…
On completely regular self-dual codes with covering radius
J. Borges, V. A. Zinoviev
We give a complete classification of self-dual completely regular codes with covering radius . For the results are almost trivial. For , by using properties of…
On new infinite families of completely regular and completely transitive codes
Joaquim Borges, Josep Rifà, Victor Zinoviev
In two previous papers we constructed new families of completely regular codes by concatenation methods. Here we determine cases in which the new codes are completely transitive. F…
On the classification of completely regular codes with covering radius two and antipodal dual
J. Borges, D. V. Zinoviev, V. A. Zinoviev
We classify all linear completely regular codes which have covering radius and whose dual are antipodal. For this, we firstly show several properties of such dual codes, whi…
On Sylvester-type constructions of Hadamard matrices and their modifications
Dmitrii Zinoviev, Victor Zinoviev
Using the ideas of concatenation construction of codes over the -ary alphabet, we modify the known generalized Sylvester-type construction of the Hadamard matrices. The new cons…
On two-weight codes
P. G. Boyvalenkov, K. V. Delchev, D. V. Zinoviev +1
We consider -ary (linear and nonlinear) block codes with exactly two distances: and . Several combinatorial constructions of optimal such codes are given. In the linear…
