A Real-time Non-contact Localization Method for Faulty Electric Energy Storage Components using Highly Sensitive Magnetometers [PDF]
arXiv, 2023 With the wide application of electric energy storage component arrays, such as battery arrays, capacitor arrays, inductor arrays, their potential safety risks have gradually drawn the public attention. However, existing technologies cannot meet the needs of non-contact and real-time diagnosis for faulty components inside these massive arrays.

Noise improvement of SNR gain in parallel array of bistable dynamic systems by array stochastic resonance [PDF]
arXiv, 2006 We report the regions where a signal-to-noise ratio (SNR) gain exceeding unity exists in a parallel uncoupled array of identical bistable systems, for both subthreshold and suprathreshold sinusoids buried in broadband Gaussian white input noise. Due to independent noise in each element of the parallel array, the SNR gain of the collective array ...

PhD Thesis on Code Modulated Interferometric Imaging System using Phased Arrays [PDF]
arXiv, 2021 This work presents techniques which can allow low-cost phased-array receivers to be reconfigured as interferometric imagers and thereby reducing cost. Since traditional phased arrays power combine incoming signals prior to digitization, orthogonal code-modulation is applied to each incoming signal using phase shifters within each front-end.

Product Processing for Tapered Sparse Arrays [PDF]
arXiv, 2021 The product processor output has recently been introduced as a spatial power spectral density estimate, unifying product arrays such as coprime arrays, nested arrays, and standard uniform line arrays. The expected value and covariance function of this estimate for a white Gaussian process was derived in previous work over these various array ...

Compressive MUSIC: Revisiting the Link Between Compressive Sensing and Array Signal Processing
IEEE Transactions on Information Theory, 2012 The multiple measurement vector (MMV) problem addresses the identification of unknown input vectors that share common sparse support. Even though MMV problems have been traditionally addressed within the context of sensor array signal processing, the ...

Attention-based distributed speech enhancement for unconstrained microphone arrays with varying number of nodes [PDF]
European Signal Processing Conference (EUSIPCO), IEEE, Aug 2021,
Dublin, Ireland, 2021 Speech enhancement promises higher efficiency in ad-hoc microphone arrays than in constrained microphone arrays thanks to the wide spatial coverage of the devices in the acoustic scene. However, speech enhancement in ad-hoc microphone arrays still raises many challenges.

Multiple Angles of Arrival Estimation using Neural Networks [PDF]
arXiv, 2020 MUltiple SIgnal Classification (MUSIC) and Estimation of signal parameters via rotational via rotational invariance (ESPRIT) has been widely used in super resolution direction of arrival estimation (DoA) in both Uniform Linear Arrays (ULA) or Uniform Circular Arrays (UCA).

Wideband Millimeter-Wave Beam Training with True-Time-Delay Array Architecture [PDF]
, 2019 Millimeter-wave communications rely on beamforming gain from both transmitters and receivers to compensate for severe propagation loss. To achieve adequate gain, beam training is required to identify propagation directions. The main challenge in beam training arises from maintaining low overhead with increased array size.
