On Communication for Distributed Babai Point Computation
Maiara F. Bollauf, Vinay A. Vaishampayan, Sueli I. R. Costa
We present a communication-efficient distributed protocol for computing the Babai point, an approximate nearest point for a random vector in a given lattic…
Multilevel constructions: coding, packing and geometric uniformity
Maiara Francine Bollauf, Ram Zamir, Sueli Irene Rodrigues Costa
Lattice and special nonlattice multilevel constellations constructed from binary codes, such as Constructions A, C, and D, have relevant applications in Mathematics (sphere packing…
Communication-Efficient Search for an Approximate Closest Lattice Point
Maiara F. Bollauf, Vinay A. Vaishampayan, Sueli I. R. Costa
We consider the problem of finding the closest lattice point to a vector in n-dimensional Euclidean space when each component of the vector is available at a distinct node in a net…
An Upper Bound for Signal Transmission Error Probability in Hyperbolic Spaces
Edson Agustini, Sueli I. R. Costa
We introduce and discuss the concept of Gaussian probability density function (pdf) for the n-dimensional hyperbolic space which has been proposed as an environment for coding and…
