Behavioral systems theory in data-driven analysis, signal processing, and control
Annual Reviews in Control, 2021 The behavioral approach to systems theory, put forward 40 years ago by Jan C. Willems, takes a representation-free perspective of a dynamical system as a set of trajectories.

Discrete Signal Processing on Graphs: Sampling Theory
IEEE Transactions on Signal Processing, 2015 We propose a sampling theory for signals that are supported on either directed or undirected graphs. The theory follows the same paradigm as classical sampling theory.

Game Theory in Signal Processing and Communications
EURASIP Journal on Advances in Signal Processing, 2009 Game theory is a branch of mathematics aimed at the modeling and understanding of resource conflict problems. Essentially, the theory splits into two branches: noncooperative and cooperative game theory. The distinction between the two is whether or not the players in the game can make joint decisions regarding the choice of strategy.

Residual feedback suppression with extended model-based postfilters
EURASIP Journal on Audio, Speech, and Music Processing, 2021 When designing closed-loop electro-acoustic systems, which can commonly be found in hearing aids or public address systems, the most challenging task is canceling and/or suppressing the feedback caused by the acoustic coupling of the transducers of such ...

Fast and precise underwater transducer characterisation utilising adaptive system identification
IET Radar, Sonar & Navigation, 2023 Characterising underwater acoustic transducers is essential to optimal signal processing in sound navigation and ranging systems. Precise characterisation allows for equalisation of the input and output hardware, resulting in improved performance of the ...

Orthogonal Time Frequency Space Modulation Based on the Discrete Zak Transform
Entropy, 2022 In orthogonal time frequency space (OTFS) modulation, information-carrying symbols reside in the delay-Doppler (DD) domain. By operating in the DD domain, an appealing property for communication arises: time-frequency (TF) dispersive channels encountered

Fast beampattern evaluation by polynomial rooting [PDF]
Advances in Radio Science, 2011 Current automotive radar systems measure the distance, the relative velocity and the direction of objects in their environment. This information enables the car to support the driver.

Context-Unsupervised Adversarial Network for Video Sensors
Sensors, 2022 Foreground object segmentation is a crucial first step for surveillance systems based on networks of video sensors. This problem in the context of dynamic scenes has been widely explored in the last two decades, but it still has open research questions ...
