Published in 2017 at "Ecology and Evolution"

DOI: 10.1002/ece3.2621

Abstract: Abstract The matched filter hypothesis proposes that the tuning of auditory sensitivity and the spectral character of calls will match in order to maximize auditory processing efficiency during courtship. In this study, we analyzed the… read more here.

Published in 2018 at "Circuits, Systems, and Signal Processing"

DOI: 10.1007/s00034-017-0562-1

Abstract: The paper develops a new interpretation of matched filtering of non-stationary signals in the fractional Fourier transform domain, which is beneficial for non-stationary/time–frequency signal processing applications. In the pursuit of establishing the theoretical and methodical… read more here.

Published in 2018 at "Measurement"

DOI: 10.1016/j.measurement.2018.07.089

Abstract: Abstract This paper proposes novel algorithms to detect pavement lane markings on two-dimensional (2D) laser images via three stages. First, a new matched filter is developed to generate strongest responses at pavement lane markings. Second,… read more here.

Published in 2019 at "Bioacoustics"

DOI: 10.1080/09524622.2018.1482786

Abstract: ABSTRACT The matched filter hypothesis proposes that the auditory sensitivity of receivers should match the spectral energy distribution of the senders’ signals. If so, receivers should be able to distinguish between species-specific and hetero-specific signals.… read more here.

Published in 2021 at "IEEE Access"

DOI: 10.1109/access.2021.3134796

Abstract: The radio frequency spectrum is getting more congested day by day due to the growth of wireless devices, applications, and the arrival of fifth generation (5G) mobile communications. This happens because the radio spectrum is… read more here.

Published in 2021 at "IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing"

DOI: 10.1109/jstars.2021.3093820

Abstract: For additive signals on Gaussian clutter, the optimal detector is a linear matched filter that is adapted to the known signal and the covariance of the background. This adaptive matched filter is widely used for… read more here.

Published in 2022 at "IEEE Signal Processing Letters"

DOI: 10.1109/lsp.2022.3195427

Abstract: In this letter, we deal with the problem of high-resolution time delay estimation (TDE) in multipath environments exploiting the matched filter (MF) outputs data. To this end, we develop a systematic post-processing framework, consisting of… read more here.

Published in 2020 at "IEEE Transactions on Aerospace and Electronic Systems"

DOI: 10.1109/taes.2020.3009508

Abstract: The adaptive matched filter (AMF) uses a number of training samples observed by the radar to estimate the unknown disturbance covariance matrix of a cell under test. In general, as the number of homogeneous training… read more here.

Published in 2022 at "IEEE Transactions on Aerospace and Electronic Systems"

DOI: 10.1109/taes.2022.3171749

Abstract: Consider an electrical dipole and a magnetic loop—co-centered and axially aligned. This compact pair of line antennas is centro-symmetric and polarization-sensitive but suffers no mutual coupling. Their “spatial matched filter” beam-steering bias will be analytically… read more here.
