Measure-preserving mappings from the unit cube to some symmetric spaces
Carlos Beltrán, Damir Ferizović, Pedro R. López-Gómez
We construct measure-preserving mappings from the -dimensional unit cube to the -dimensional unit ball and the compact rank one symmetric spaces, namely the -dimensional s…
Statistical characterization of the chordal product determinant of Grassmannian codes
Javier Álvarez-Vizoso, Carlos Beltrán, Diego Cuevas +3
We consider the chordal product determinant, a measure of the distance between two subspaces of the same dimension. In information theory, collections of elements in the complex Gr…
Constellations on the Sphere with Efficient Encoding-Decoding for Noncoherent Communications
Javier Álvarez-Vizoso, Carlos Beltrán, Ignacio Santamaria +2
In this paper, we propose a new structured Grassmannian constellation for noncoherent communications over single-input multiple-output (SIMO) Rayleigh block-fading channels. The co…
A lower bound for the logarithmic energy on and for the Green energy on
Carlos Beltrán, Fátima Lizarte
We show an alternative proof of the sharpest known lower bound for the logarithmic energy on the unit sphere . We then generalize this proof to get new lower bounds f…
