Variational Bayesian Data Detection for Multiuser MIMO Systems Corrupted by Phase Noises
Toan-Van Nguyen, Duy H. N. Nguyen
Phase noise (PN), arising from imperfect local oscillators, introduces multiplicative distortions that degrade the performance of communication systems. In uplink multiuser multipl…
Data-Aided Asynchronous OFDM Integrated Sensing and Communications: A Mean-Field Variational Bayes Approach
Van-Chung Luu, Nuria González Prelcic, Duy H. N Nguyen
Integrated sensing and communication (ISAC) is regarded as a key technology for sixth-generation wireless networks, allowing sensing and communication operations to jointly utilize…
Secure Rate-Splitting and RIS Beamforming with Untrusted Energy Harvesting Receivers
Hamid Reza Hashempour, Le-Nam Tran, Duy H. N. Nguyen +1
We consider a reconfigurable intelligent surface (RIS)-assisted heterogeneous network comprising legitimate information-harvesting receivers (IHRs) and untrusted energy-harvesting…
Semi-Gridless Variational Bayes Channel Estimation in XL-MIMO: Near-Field Modeling and Inference
Van-Chung Luu, Toan-Van Nguyen, Nuria González-Prelcic +1
Extremely large antenna arrays and high-frequency operation are two key technologies that advance performance metrics such as higher data rates, lower latency, and wider coverage i…

MIMO Detection with Spatial Sigma-Delta ADCs: A Variational Bayesian Approach
Toan-Van Nguyen, Sajjad Nassirpour, Italo Atzeni +3
The spatial Sigma-Delta () architecture can be leveraged to reduce the quantization noise and enhance the effective resolution of few-bit analog-to-digital converters (ADCs) at…
User-Centric Beam Selection and Precoding Design for Coordinated Multiple-Satellite Systems
Vu Nguyen Ha, Duy H. N. Nguyen, Juan C. -M. Duncan +7
This paper introduces a joint optimization framework for user-centric beam selection and linear precoding (LP) design in a coordinated multiple-satellite (CoMSat) system, employing…
Doubly 1-Bit Quantized Massive MIMO
Italo Atzeni, Antti Tölli, Duy H. N. Nguyen +1
Enabling communications in the (sub-)THz band will call for massive multiple-input multiple-output (MIMO) arrays at either the transmit- or receive-side, or at both. To scale down…
