Fisher information distance: a geometrical reading
Sueli I. R. Costa, Sandra A. Santos, João E. Strapasson
This paper is a strongly geometrical approach to the Fisher distance, which is a measure of dissimilarity between two probability distribution functions. The Fisher distance, as we…
On the existence of rotated -lattices constructed via Galois extensions
Grasiele Cristiane Jorge, Sueli Irene Rodrigues Costa
In this paper we construct families of rotated -lattices which may be suitable for signal transmission over both Gaussian and Rayleigh fading channels via subfields of cycloto…
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…
On projections of arbitrary lattices
Antonio Campello, João Strapasson, Sueli Costa
In this paper we prove that given any two point lattices and , there is a set of vectors s…
Curves on torus layers and coding for continuous alphabet sources
Antonio Campello, Cristiano Torezzan, Sueli I. R. Costa
In this paper we consider the problem of transmitting a continuous alphabet discrete-time source over an AWGN channel. The design of good curves for this purpose relies on geometri…
