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…
Rate Splitting in MIMO RIS-assisted Systems with Hardware Impairments and Improper Signaling
Mohammad Soleymani, Ignacio Santamaria, Eduard Jorswieck
In this paper, we propose an optimization framework for rate splitting (RS) techniques in multiple-input multiple-output (MIMO) reconfigurable intelligent surface (RIS)-assisted sy…
Benefits of improper signaling for underlay cognitive radio
Christian Lameiro, Ignacio Santamaría, Peter J. Schreier
In this letter we study the potential benefits of improper signaling for a secondary user (SU) in underlay cognitive radio networks. We consider a basic yet illustrative scenario i…
