Low-Latency LDPC Decoding Based on Consensus and Return Residual Belief Propagation
Allan E. Feitosa, Rodrigo C. de Lamare
We propose two new decoding algorithms for low-density parity-check (LDPC) codes. The Consensus and Return residual belief propagation (C&R-RBP) algorithm reduces the number of ite…
Study of Iterative Detection and Decoding for {Mixed Near- and Far-Field} XL-MIMO Systems
Nayyab Haider, Rodrigo C. de Lamare
Extra-large multiple-input multiple-output (XL-MIMO) systems {serving users across near-field and far-field regions} experience spherical wavefront propagation that provides enhanc…
Shape Adaptive Reconfigurable Holographic Surfaces
Jalal Jalali, Mostafa Darabi, Rodrigo C. de Lamare
The evolution of wireless networks toward sixth-generation (6G) is driving demand for intelligent, flexible, and energy-efficient propagation control. Reconfigurable holographic su…
Gaussian-trigonometric functional link artificial neural network: design and analysis
Jie Wang, Lu Lu, Yi Yu +3
This paper proposes a Gaussian function-based trigonometric functional link artificial neural network (GTFLN) filter for linear-in-the-parameters nonlinear filtering. Compared with…
Study of Multiuser Scheduling Based on User Satisfaction for MU-MIMO Systems
Ahmed M. Nor, Lukas T. N. Landau, E. Veronica Belmega +1
Scheduling in multiuser multiple input multiple output (MU-MIMO) systems is essential for efficient resource allocation and overall performance enhancement. In this work, a multius…
Study of Mixed-Integer Optimization Based on Graph-Based Decomposition for Cell-Free Networks
Julio Cesar Cardoso Tesolin, Rodrigo C. de Lamare
This letter develops a radio access network (RAN) framework for mixed discrete-continuous optimization problems that arise in user-centric cell=free massive multiple-antenna networ…
Study of Graph-Based Search for Energy-Efficient Clustering in Cell-Free Massive MIMO Networks
Julio Cesar Cardoso Tesolin, Rodrigo C. de Lamare
This paper investigates energy-efficient clustering in user-centric cell-free massive MIMO networks, addressing the access point clustering and power allocation problems via a mixe…
Study of Code-Aided Channel Estimation for Metasurface-Based Holographic MIMO Systems
Roberto C. G. Porto, Rodrigo C. de Lamare
This work proposes an iterative code-aided detection, decoding, and channel estimation scheme for metasurface-based holographic MIMO systems employing stacked intelligent metasurfa…
Channel Chart Location Privacy Based on Geo-Indistinguishability
Atsu Kokuvi Angélo Passah, Rodrigo C. de Lamare, Arsenia Chorti
Channel charting enables location-based services (LBSs) without requiring explicit position information by using pseudo-locations from the channel chart. While this property implie…
