Zone-Based Interference Management for Underlay Spectrum Sharing in Cell-Free Networks
Mariana M. Ferreira, Juno V. Saraiva, Yuri C. B. Silva +4
Underlay spectrum sharing enables flexible coexistence between a primary network (PN) and a secondary network (SN), but inter-network interference remains a critical limiting facto…
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…
Decoupling and Matching Strategies for Compact Antenna Arrays
F. Estevão S. Pereira, Josef A. Nossek, F. Rodrigo P. Cavalcanti
Antenna arrays have been used in various applications and have become an important tool to achieve high spectral efficiency in wireless communications. Its use brings to the commun…
