IET Signal Processing, Volume 16, Issue 7, Page 800-810, September 2022., 2022 Abstract This paper investigates an advanced effective signal processing technique to suppress noise, addressing a modern high‐performance detection in the field of radar sensing. To achieve a higher accuracy, the frequency modulated continuous wave radar is taken as a case study to derive the algorithm based on Karhunen ‐ Loève transform (KLT) before ...

Dynamical Behavior of Hybrid Propagation of Computer Viruses
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Considering the horizontal and vertical propagation of computer viruses over the Internet, this article proposes a hybrid susceptible‐latent‐breaking‐recovered‐susceptible (SLBRS) model. Through mathematical analysis of the model, two equilibria (virus‐free and virose equilibria) and their global stabilities are both proved depending on the basic ...

An iterative MPD‐CNN structure for massive MIMO detection under correlated noise channels
IET Communications, Volume 15, Issue 12, Page 1632-1641, July 2021., 2021 Abstract In massive multiple‐input multiple‐output (MIMO) systems, most of the existing detection work mainly assumes that the channel is the additive white Gaussian noise (AWGN). However, this assumption is difficult to apply to practical communication scenarios.

Complexity, Volume 2021, Issue 1, 2021., 2021 This paper aims to explore coevolution of emotional contagion and behavior for microblog sentiment analysis. Accordingly, a deep learning architecture (denoted as MSA‐UITC) is proposed for the target microblog. Firstly, the coevolution of emotional contagion and behavior is described by the tie strength between microblogs, that is, with the spread of ...

Modeling and Analysis of Dynamic Social Ties in D2D Collaborative Video Transmission
Discrete Dynamics in Nature and Society, Volume 2020, Issue 1, 2020., 2020 Social networks are one of the main carriers of information diffusion. Changes in social ties will affect the quality of Device‐to‐Device (D2D) communications especially the video transmission. For further improving the communication utility of users, it is of great significance to effectively integrate D2D communications and social networks.

Complexity, Volume 2020, Issue 1, 2020., 2020 This paper investigates the observer‐based structural balance control for a class of complex dynamical networks. Generally speaking, a complete complex dynamical network is composed of two coupled subsystems, which are called node subsystem (NS) and connection relationship subsystem (CS), respectively.

Adaptive State Observer Design for Dynamic Links in Complex Dynamical Networks
Computational Intelligence and Neuroscience, Volume 2020, Issue 1, 2020., 2020 The state observer for dynamic links in complex dynamical networks (CDNs) is investigated by using the adaptive method whether the networks are undirected or directed. In this paper, a complete network model is proposed, which is composed of two coupled subsystems called nodes subsystem and links subsystem, respectively.

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018 Quantifying the decomposition of soil organic carbon (SOC) fractions under climate change is essential to predict carbon‐climate feedbacks. The accuracy and utility of a combustion module coupled with cavity ring‐down spectroscopy (CM‐CRDS) system were assessed for simultaneously determining SOC and δ13C‐SOC. Using a range of standard materials as well

Stabilization and Synchronization of Memristive Chaotic Circuits by Impulsive Control
Complexity, Volume 2017, Issue 1, 2017., 2017 The purpose of this note is to study impulsive control and synchronization of memristor based chaotic circuits shown by Muthuswamy. We first establish a less conservative sufficient condition for the stability of memristor based chaotic circuits. After that, we discuss the effect of errors on stability.
