6. Novas Ferramentas para Processamento
de Sinais em Corpos Finitos
In this paper, the concept of Galoisian
ring is introduced aiming at the development of new tools for the processing
of signals defined over finite fields.
The notions of k-trigonometric functions over the finite field GF(p^m) are
defined, and a few of its properties investigated. Some applications of the
new tools are suggested.
