IRS-Assisted Massive MIMO-NOMA Networks: Exploiting Wave Polarization
Arthur S. de Sena, Pedro H. J. Nardelli, Daniel B. da Costa +5
A dual-polarized intelligent reflecting surface (IRS) can contribute to a better multiplexing of interfering wireless users. In this paper, we use this feature to improve the perfo…

Deep Reinforcement Learning for QoS-Constrained Resource Allocation in Multiservice Networks
Juno V. Saraiva, Iran M. Braga, Victor F. Monteiro +4
In this article, we study a Radio Resource Allocation (RRA) that was formulated as a non-convex optimization problem whose main aim is to maximize the spectral efficiency subject t…
