Codificação espaço-temporal
(Universidade Estadual Paulista (Unesp), 2012-08-31)
Neste trabalho nós abordamos alguns dos principais aspectos relacionados a codi- cação espaço-temporal e as ferramentas algébricas envolvidas na projeção de códigos baseados em álgebras de divisão cíclica. Apresentaremos ...
Construction of perfect space-time codes
(2013-04-29)
In this work, we propose an innovative methodology to extend the construction of minimum and non-minimum delay perfect codes as a subset of cyclic division algebras over ℚ(ζ3), where the signal constellations are isomorphic ...

On the construction of perfect codes from HEX signal constellations
(Pergamon-Elsevier B.V. Ltd, 2012-12-01)
Recently, minimum and non-minimum delay perfect codes were proposed for any channel of dimension n. Their construction appears in the literature as a subset of cyclic division algebras over Q(zeta(3)) only for the dimension ...

The de Rham Witt complex, cohomological kernels and p(m)-extensions in characteristic p
(2018)
In earlier work the authors determined the Brauer kernel of extensions of degree p in characteristic p > 2 where the Galois group is a semidirect product of order ps for sl(p - 1). This result is extended here and tools ...
