A super transformed nested array with reduced mutual coupling for direction of arrival estimation of non‐circular signals

open access: yesIET Radar, Sonar & Navigation, 2022
Recently, sparse linear arrays have aroused significant attention because they can provide increased degrees of freedom (DOFs) and enlarged inter‐element spacing, which are the critical factors to improve the accuracy of direction of arrival (DOA ...

Target localisation from bistatic range measurements in multistatic passive radar using MDS

open access: yesThe Journal of Engineering, 2019
The target localisation in a multistatic passive radar system using bistatic range measurements from multiple transmitter–receiver pairs is considered. A novel closed-form solution employing multidimensional scaling (MDS) analysis technique is proposed ...

A DOA Estimation Method for Sparse Array Based on DFT Spectrum of Received Signals

open access: yesIEEE Access, 2022
In the direction of arrival (DOA) estimation of sparse array received signals, the estimation accuracy of the grid search method in compressed sensing is improved with the increase of over-complete redundant dictionary elements.

Nucleosome Switches [PDF]

open access: yesPhysical Review Letters, 2008
We present a statistical-mechanical model for the positioning of nucleosomes along genomic DNA molecules as a function of the strength of the binding potential and the chemical potential of the nucleosomes. We show that a significant section of the DNA is composed of two-level nucleosome switching regions where the nucleosome distribution undergoes a ...

Symmetric flipped nested array for mixed near‐field and far‐field non‐circular source localisation

open access: yesIET Radar, Sonar & Navigation, 2022
As it is known, existing mixed near‐field and far‐field non‐circular source localisation rely on the uniform linear array (ULA). Compared with the ULA, the sparse array can obtain more consecutive lags and a larger physical array aperture.

Artificial noise-assisted physical layer security in D2D-enabled cellular networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2017
Device-to-device (D2D) communication has been deemed as a promising technology in the next generation 5G wireless communication. Due to the openness nature of the transmission medium, secure transmission is also a critical issue in the D2D-enabled ...

Switching Portfolios [PDF]

open access: yesInternational Journal of Neural Systems, 1997
A constant rebalanced portfolio is an asset allocation algorithm which keeps the same distribution of wealth among a set of assets along a period of time. Recently, there has been work on on-line portfolio selection algorithms which are competitive with the best constant rebalanced portfolio determined in hindsight (Cover, 1991; Helmbold et al., 1996;

Anti-deception: reliable EEG-based biometrics with real-time capability from the neural response of face rapid serial visual presentation

open access: yesBioMedical Engineering OnLine, 2018
Background The electroencephalogram (EEG) signal represents a subject’s specific brain activity patterns and is considered as an ideal biometric given its superior invisibility, non-clonality, and non-coercion.
