QoS-Aware User Scheduling in Crowded XL-MIMO Systems Under Non-Stationary Multi-State LoS/NLoS Channels
Joao Henrique Inacio de Souza, Jose Carlos Marinello, Abolfazl Amiri +1
Providing minimum quality-of-service (QoS) in crowded wireless communications systems, with high user density, is challenging due to the network structure with limited transmit pow…
Throughput and Latency in the Distributed Q-Learning Random Access mMTC Networks
Giovanni Maciel Ferreira Silva, Taufik Abrao
In mMTC mode, with thousands of devices trying to access network resources sporadically, the problem of random access (RA) and collisions between devices that select the same resou…
Decentralized Design of Fast Iterative Receivers for Massive and Extreme-Large MIMO Systems
Victor Croisfelt, Taufik Abrão, Abolfazl Amiri +2
Despite the extensive use of a centralized approach to design receivers at the base station for massive multiple-input multiple-output (M-MIMO) systems, their actual implementation…
Exploring the Non-Overlapping Visibility Regions in XL-MIMO Random Access Protocol
José Carlos Marinello Filho, Glauber Brante, Richard Demo Souza +1
The recent extra-large scale massive multiple-input multiple-output (XL-MIMO) systems are seen as a promising technology for providing very high data rates in increased user-densit…
Mixed Gibbs Sampling Detector in High-Order Modulation Large-Scale MIMO Systems
Alex Mussi, Taufik Abrão
A neighborhood restricted Mixed Gibbs Sampling (MGS) based approach is proposed for low-complexity high-order modulation large-scale Multiple-Input Multiple-Output (LS-MIMO) detect…
Quasi-Distributed Antenna Selection for Spectral Efficiency Maximization in Subarray Switching XL-MIMO Systems
Joao Henrique Inacio de Souza, Abolfazl Amiri, Taufik Abrao +2
In this paper, we consider the downlink (DL) of a zero-forcing (ZF) precoded extra-large scale massive MIMO (XL-MIMO) system. The base-station (BS) operates with limited number of…
