A note on sub-orthogonal lattices
João Eloir Strapasson
It is shown that, given any -dimensional lattice , there is a lattice sequence , , with sub-orthogonal lattice , converging to (unless…
A heuristic approach for designing cyclic group codes
João E. Strapasson, Cristiano Torezzan
In this paper we propose a heuristic technique for distributing points on the surface of a unit n-dimensional Euclidean sphere, generated as the orbit of a finite cyclic subgroup o…
Quasi-perfect codes in the metric
João E. Strapasson, Grasiele C. Jorge, Antonio Campello +1
We consider quasi-perfect codes in over the metric, . Through a computational approach, we determine all radii for which there are linear…
Optimum Commutative Group Codes
Cristiano Torezzan, João E. Strapasson, Sueli I. R. Costa +1
A method for finding an optimum -dimensional commutative group code of a given order is presented. The approach explores the structure of lattices related to these codes and…
