Rank Constrained Precoding for the Downlink of mmWave Massive MIMO Hybrid Systems
(Institute of Electrical and Electronics Engineers, 2021-02-11)
[Abstract]
The hybrid design of precoding schemes for millimeter-wave communications allows exploiting the gains by using large antenna array with an affordable hardware cost and power consumption. In this work, we present ...
From Pre-Quantum to Post-Quantum IoT Security: A Survey on Quantum-Resistant Cryptosystems for the Internet of Things
(IEEE, 2020)
[Absctract]: Although quantum computing is still in its nascent age, its evolution threatens the most popular public-key encryption systems. Such systems are essential for today's Internet security due to their ability for ...
Fake News, Disinformation, and Deepfakes: Leveraging Distributed Ledger Technologies and Blockchain to Combat Digital Deception and Counterfeit Reality
(IEEE, 2020-03)
[Absctract]: The rise of ubiquitous deepfakes, misinformation, disinformation, and post-truth, often referred to as fake news, raises concerns over the role of the Internet and social media in modern democratic societies. ...
A Real-Time Implementation of the Mobile WiMAX ARQ and Physical Layer
(Springer, 2015)
[Abstract] This paper presents an innovative software-defined radio architecture for the real-time implementation of WiMAX transceivers. The architecture consists of commercially available field-programmable gate array and ...
QoS constrained power minimization in the multiple stream MIMO broadcast channel
(Elsevier, 2018-02)
[Abstract]: This work addresses the design of optimal linear transmit filters for the Multiple Input-Multiple Output (MIMO) Broadcast Channel (BC) when several spatial streams are allocated to each user. We further consider ...
QoS constrained power minimization in the MISO broadcast channel with imperfect CSI
(Elsevier, 2017-02)
[Abstract]: In this paper we consider the design of linear precoders and receivers in a Multiple-Input Single-Output (MISO) Broadcast Channel (BC). We aim to minimize the transmit power while meeting a set of per-user ...
Design of Linear Precoders for Correlated Sources in MIMO Multiple Access Channels
(Institute of Electrical and Electronics Engineers, 2018-12)
[Abstract]: This paper focuses on distributed linear precoding when users transmit correlated information over a fading multiple-input and multiple-output multiple access channel. The precoders are optimized in order to ...
Channel Covariance Identification in FDD Massive MIMO Systems
(IEEE, 2018-11)
[Abstract]: Many channel estimation methods in Massive MIMO FDD systems usually rely on the knowledge of the channel covariance matrix to operate. However, in real scenarios, this covariance is not known beforehand, and ...
A Practical Evaluation of Commercial Industrial Augmented Reality Systems in an Industry 4.0 Shipyard
(IEEE, 2018)
[Absctract]: The principles of the Industry 4.0 are guiding manufacturing companies toward more automated and computerized factories. Such principles are also applied in shipbuilding, which usually involves numerous complex ...
Transmission of Spatio-Temporal Correlated Sources Over Fading Multiple Access Channels With DQLC Mappings
(Institute of Electrical and Electronics Engineers, 2019-08)
[Abstract]: The design of zero-delay Joint Source-Channel Coding (JSCC) schemes for the transmission of correlated information over fading Multiple Access Channels (MACs) is an interesting problem for many communication ...
