An Array Recursive Least-Squares Algorithm With Generic Nonfading Regularization Matrix
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
We present a novel array RLS algorithm with forgetting factor that circumvents the problem of fading regularization, inherent to the standard exponentially-weighted RLS, by allowing for time-varying regularization matrices ...
Optimal Suffix Sorting And Lcp Array Construction For Constant Alphabets
(Elsevier Science BVAmsterdam, 2017)
Revisiting The Kronecker Array Transform

Design of 2D planar sparse binned arrays based on the Coarray analysis
(2021-12-01)
The analysis of the beampattern is the base of sparse arrays design process. However, in the case of bidimensional arrays, this analysis has a high computational cost, turning the design process into a long and complex ...
Design of ultrasonic synthetic aperture imaging systems based on a non-grid 2D sparse array
(2021-12-01)
This work provides a guide to design ultrasonic synthetic aperture systems for non-grid two-dimensional sparse arrays such as spirals or annular segmented arrays. It presents an algorithm that identifies which elements ...
Fast Transforms for Acoustic Imaging-Part II: Applications
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
In Part I [""Fast Transforms for Acoustic Imaging-Part I: Theory,"" IEEE TRANSACTIONS ON IMAGE PROCESSING], we introduced the Kronecker array transform (KAT), a fast transform for imaging with separable arrays. Given a ...
Fast Transforms for Acoustic Imaging-Part I: Theory
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
The classical approach for acoustic imaging consists of beamforming, and produces the source distribution of interest convolved with the array point spread function. This convolution smears the image of interest, significantly ...
DOA Estimation using Random Linear Arrays via Compressive Sensing
(Institute of Electrical and Electronics Engineers, 2014-08)
In this article we analyze the performance of nonuniform linear arrays for Direction of Arrival (DOA) estimation. We use different classes of sparse recovery algorithms to estimate the direction of arrival of the signal ...
