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 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…

On q-ary codes with two distances d and d+1
P. Boyvalenkov, K. Delchev, D. Zinoviev +1
The -ary block codes with two distances and are considered. Several constructions of such codes are given, as in the linear case all codes can be obtained by a simple…
