RSMA for Dual-Polarized Massive MIMO Networks: A SIC-Free Approach

no code implementations9 Dec 2022 Arthur S. de Sena, Pedro H. J. Nardelli, Daniel B. da Costa, Petar Popovski, Constantinos B. Papadias, Merouane Debbah

Aiming at overcoming practical issues of successive interference cancellation (SIC), this paper proposes a dual-polarized rate-splitting multiple access (RSMA) technique for a downlink massive multiple-input multiple-output (MIMO) network.

Rate-Splitting Multiple Access and its Interplay with Intelligent Reflecting Surfaces

no code implementations24 May 2022 Arthur S. de Sena, Pedro H. J. Nardelli, Daniel B. da Costa, Petar Popovski, Constantinos B. Papadias

Rate-splitting multiple access (RSMA) has recently appeared as a powerful technique for improving the downlink performance of multiple-input multiple-output (MIMO) systems.

IRS-Assisted Massive MIMO-NOMA Networks with Polarization Diversity

no code implementations27 May 2021 Arthur S. de Sena, Pedro H. J. Nardelli, Daniel B. da Costa, F. Rafael M. Lima, Liang Yang, Petar Popovski, Zhiguo Ding, Constantinos B. Papadias

In this paper, the appealing features of a dual-polarized intelligent reflecting surface (IRS) are exploited to improve the performance of dual-polarized massive multiple-input multiple-output (MIMO) with non-orthogonal multiple access (NOMA) under imperfect successive interference cancellation (SIC).

Understanding UAV-Based WPCN-Aided Capabilities for Offshore Monitoring Applications

1 code implementation23 Dec 2020 Dick Carrillo, Konstantin Mikhaylov, Pedro J. Nardelli, Sergey Andreev, Daniel B. da Costa

Despite the immense progress in the recent years, efficient solutions for monitoring remote areas are still missing today.

IRS-Assisted Massive MIMO-NOMA Networks: Exploiting Wave Polarization

no code implementations7 Dec 2020 Arthur S. de Sena, Pedro H. J. Nardelli, Daniel B. da Costa, F. Rafael M. Lima, Liang Yang, Petar Popovski, Zhiguo Ding, Constantinos B. Papadias

By considering the downlink of a multi-cluster scenario, the IRSs assist the base station (BS) to multiplex subsets of users in the polarization domain.

What Role Do Intelligent Reflecting Surfaces Play in Multi-Antenna Non-Orthogonal Multiple Access?

no code implementations20 Sep 2020 Arthur S. de Sena, Dick Carrillo, Fang Fang, Pedro H. J. Nardelli, Daniel B. da Costa, Ugo S. Dias, Zhiguo Ding, Constantinos B. Papadias, Walid Saad

Massive multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA) are two key techniques for enabling massive connectivity in future wireless networks.
