MIMO radar techniques: two-stage constant false alarm rate detection for fast-fluctuating targets
The Journal of Engineering, 2019 Here, the authors analyse a two-step constant false alarm rate (CFAR) detection problem in distributed sensor system (e.g. statistical multiple-input multiple-output (MIMO) radar) for fast-fluctuating targets (TS-AMF-II).

Graphon Signal Processing [PDF]
IEEE Transactions on Signal Processing, 2021 Graphons are infinite-dimensional objects that represent the limit of convergent sequences of graphs as their number of nodes goes to infinity. This paper derives a theory of graphon signal processing centered on the notions of graphon Fourier transform and linear shift invariant graphon filters, the graphon counterparts of the graph Fourier transform ...

Graph signal processing with categorical perspective [PDF]
arXiv, 2023 In this paper, we propose a framework for graph signal processing using category theory. The aim is to generalize a few recent works on probabilistic approaches to graph signal processing, which handle signal and graph uncertainties.

Reversible Joint Hilbert and Linear Canonical Transform Without Distortion [PDF]
IEEE Transactions on Signal Processing, Volume 61, Issue 19,
Oct.1, 2013, 2017 Generalized analytic signal associated with the linear canonical transform (LCT) was proposed recently by Fu and Li ["Generalized Analytic Signal Associated With Linear Canonical Transform," Opt. Commun., vol. 281, pp. 1468-1472, 2008]. However, most real signals, especially for baseband real signals, cannot be perfectly recovered from their ...

To further understand graph signals [PDF]
arXiv, 2022 Graph signal processing (GSP) is a framework to analyze and process graph-structured data. Many research works focus on developing tools such as Graph Fourier transforms (GFT), filters, and neural network models to handle graph signals. Such approaches have successfully taken care of ``signal processing'' in many circumstances.

Learning Frame Similarity using Siamese networks for Audio-to-Score Alignment [PDF]
, 2020 Audio-to-score alignment aims at generating an accurate mapping between a performance audio and the score of a given piece. Standard alignment methods are based on Dynamic Time Warping (DTW) and employ handcrafted features, which cannot be adapted to ...

Driver fatigue monitoring system using support vector machines [PDF]
, 2012 Driver fatigue is one of the leading causes of traffic accidents. This paper presents a real-time non-intrusive fatigue monitoring system which exploits the driver's facial expression to detect and alert fatigued drivers.

System Realization of Broad Band Digital Beam Forming for Digital Array Radar
Leida xuebao, 2013 Broad band Digital Beam Forming (DBF) is the key technique for the realization of Digital Array Radar (DAR). We propose the method of combination realization of the channel equalization and DBF time delay filter function by using adaptive Sample Matrix ...
