A Scalable Approach to Independent Vector Analysis by Shared Subspace Separation for Multi-Subject fMRI Analysis
(MDPI, 2023-06)
[Abstract]: Joint blind source separation (JBSS) has wide applications in modeling latent structures across multiple related datasets. However, JBSS is computationally prohibitive with high-dimensional data, limiting the ...
Eye State Detection Using Frequency Features from 1 or 2-Channel EEG
(World Scientific Publishing, 2023)
[Abstract]: Brain–computer interfaces (BCIs) establish a direct communication channel between the human brain and external devices. Among various methods, electroencephalography (EEG) stands out as the most popular choice ...
Lattice-Based Analog Mappings for Low-Latency Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers, 2023-10-01)
[Abstract]: We consider the transmission of spatially correlated analog information in a wireless sensor network (WSN) through fading single-input and multiple-output (SIMO) multiple access channels (MACs) with low-latency ...
Deep Contextual Bandit and Reinforcement Learning for IRS-Assisted MU-MIMO Systems
(Institute of Electrical and Electronics Engineers, 2023-07)
[Abstract]: The combination of multiple-input multiple-output (MIMO) systems and intelligent reflecting surfaces (IRSs) is foreseen as a critical enabler of beyond 5G (B5G) and 6G. In this work, two different approaches ...
Alternating Minimization for Wideband Multiuser IRS-Aided MIMO Systems Under Imperfect CSI
(Institute of Electrical and Electronics Engineers, 2023-11-28)
[Abstract]: This work focuses on wideband intelligent reflecting surface (IRS)-aided multiuser MIMO systems. One of the major challenges of this scenario is the joint design of the frequency-dependent base station (BS) ...
A Rank-Constrained Coordinate Ascent Approach to Hybrid Precoding for the Downlink of Wideband Massive (MIMO) Systems
(Institute of Electrical and Electronics Engineers, 2023-12)
[Abstract]: An innovative approach to hybrid analog-digital precoding for the downlink of wideband massive MIMO systems is developed. The proposed solution, termed Rank-Constrained Coordinate Ascent (RCCA), starts seeking ...
