The Hartley Transform in a Finite Field
Ricardo M. Campello de Souza, H. M. de Oliveira, A. N. Kauffman · Journal of Communication and Information Systems · 1999
In this paper, the k-trigonometric functions over the Galois Field GF(q) are introduced and their main properties derived. This leads to the definition of the cask(.) function over GF(q), which in turn leads to a finite field Hartley Transform. The main properties of this new discrete transform are presented and areas for possible applications are mentioned.
