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…
Constrained Riemannian Noncoherent Constellations for the MIMO Multiple Access Channel
Javier Álvarez-Vizoso, Diego Cuevas, Carlos Beltrán +3
We consider the design of multiuser constellations for a multiple access channel (MAC) with K users, with M antennas each, that transmit simultaneously to a receiver equipped with…
On the Entropy Computation of Large Complex Gaussian Mixture Distributions
Su Min Kim, Tan Tai Do, Tobias J. Oechtering +1
The entropy computation of Gaussian mixture distributions with a large number of components has a prohibitive computational complexity. In this paper, we propose a novel approach e…
