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 ...
New Computation of Resolving Connected Dominating Sets in Weighted Networks
(M D P I AG, 2019-11-29)
[Abstract] In this paper we focus on the issue related to finding the resolving connected dominating sets (RCDSs) of a graph, denoted by G. The connected dominating set (CDS) is a connected subset of vertices of G selected ...
Analog Transmission of Spatio-Temporal Correlated Sources Over MAC With Modulo Mappings
(Institute of Electrical and Electronics Engineers, 2018-05)
[Abstract]: Modulo mappings is an appealing scheme for the analog transmission of spatially correlated discrete-time analog source symbols over multiple access channels. In this letter, we show that the modulo mappings are ...
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) ...
Transmission of Analog Information Over the Multiple Access Relay Channel Using Zero-Delay Non-Linear Mappings
(Institute of Electrical and Electronics Engineers, 2019-04-04)
[Abstract]: We consider the zero-delay encoding of discrete-time analog information over the Multiple Access Relay Channel (MARC) using non-linear mapping functions. On the one hand, zero-delay non-linear mappings are ...
Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems
(IEEE, 2018-05)
[Abstract]: Configuring the hybrid precoders and combiners in a millimeter wave multiuser multiple-input multiple-output system is challenging in frequency selective channels. In this paper, we develop a system that uses ...
A Review on Industrial Augmented Reality Systems for the Industry 4.0 Shipyard
(IEEE, 2018)
[Absctract]: Shipbuilding companies are upgrading their inner workings in order to create Shipyards 4.0, where the principles of Industry 4.0 are paving the way to further digitalized and optimized processes in an integrated ...
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 ...
