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…
Revisiting XL-MIMO Channel Estimation: When Dual-Wideband Effects Meet Near Field
Anzheng Tang, Jun-Bo Wang, Yijin Pan +4
The deployment of extremely large antenna arrays (ELAAs) in extremely large-scale multiple-input multiple-output (XL-MIMO) systems introduces significant near-field effects, such a…
Efficient Robust Adaptive Beamforming Based on Spatial Sampling with Virtual Sensors
S. Mohammedzadeh, R. de Lamare
Robust adaptive beamforming (RAB) based on interference-plus-noise covariance (IPNC) matrix reconstruction can experience serious performance degradation in the presence of look di…
Spatially Non-Stationary XL-MIMO Channel Estimation: A Three-Layer Generalized Approximate Message Passing Method
Anzheng Tang, Jun-Bo Wang, Yijin Pan +4
In this paper, channel estimation problem for extremely large-scale multi-input multi-output (XL-MIMO) systems is investigated with the considerations of the spherical wavefront ef…
Study of Iterative Detection and Decoding for RIS-Aided Multiuser Multi-Antenna Systems
R. Porto, R. C. de Lamare
We present a novel iterative detection and decoding (IDD) scheme for Reconfigurable Intelligent Surface (RIS)-assisted multiuser multiple-antenna systems. The proposed approach int…
Study of Weighted Residual Layered Belief Propagation for Decoding of LDPC Codes
H. Touati, R. C. de Lamare
In this work, we investigate the decoding of Low-Density Parity-Check (LDPC) codes using informed dynamic scheduling algorithms that require a reduced number of iterations. In part…
