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…
Dirac inequality for highest weight Harish-Chandra modules II
Pavle Pandžić, Ana Prlić, Vladimír Souček +1
Let be a connected simply connected noncompact exceptional simple Lie group of Hermitian type. In this paper, we work with the Dirac inequality which is a very useful tool for…
Dirac inequality for highest weight Harish-Chandra modules I
Pavle Pandžić, Ana Prlić, Vladimír Souček +1
Let be a connected simply connected noncompact classical simple Lie group of Hermitian type. Then has unitary highest weight representations. The proof of the classificatio…
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…
Hyperplane section of the complex Cayley plane as the homogeneous space
Peter Franek, Karel Pazourek, Vít Tuček
We prove that the exceptional complex Lie group has a transitive action on the hyperplane section of the complex Cayley plane . Our proof is direct and constru…
