This work is concerned with determining optimal sensor placements that allow for an
accurate location estimate of structured signal sources, taking into account the expected …

A large-scale fully digital receive antenna array can provide very high-resolution direction of
arrival (DOA) estimation, but resulting in a significantly high RF-chain circuit cost. Thus, a …

Speech enhancement is a core problem in audio signal processing with commercial
applications in devices as diverse as mobile phones, conference call systems, smart …

Acoustic sensing from a multi-rotor drone is heavily degraded by the strong ego-noise
produced by the rotating motors and propellers. To address this problem, we propose a …

We propose a time difference of arrival (TDOA) estimation framework based on time-
frequency inter-channel phase difference (IPD) to count and localize multiple acoustic …

The multiple signal classification (MUSIC) algorithm based on spatial time-frequency
distribution (STFD) has been investigated for direction of arrival (DOA) estimation of closely …

The problem of speaker tracking in noisy and reverberant enclosures is addressed in this
paper. We present a hybrid algorithm, combining traditional tracking schemes with a new …

In this paper, the problem of joint multi-pitch and direction-of-arrival (DOA) estimation for
multichannel harmonic sinusoidal signals is considered. A spatio-temporal matrix signal …

This article presents a two-step dynamic mode decomposition (TSDMD) approach to
estimate the direction of arrival (DOA) and frequency for multiple narrow-band sources with …

For a passive direction of arrival (DOA) measurement system using massive multiple input
multiple output (MIMO), it is mandatory to infer whether the emitter exists or not before …
