This paper considers the problem of identifying multiple sound sources from acoustical
measurements obtained by an array of microphones. The problem is solved via maximum …

Direction of arrival (DOA) estimation of multiple sources using an antenna array becomes
very important in wireless communications. It is well known that the quality of the DOA …

In this paper, maximum likelihood estimator is proposed for passive localization of
narrowband sources in the spherical coordinates (azimuth, elevation, and range). We adapt …

This paper investigates the three-dimensional passive source localization problem by a
system of multiple antenna arrays. It is well-known that centralized and coherent processing …

Focused beamformers are widely used in passive underwater acoustic localization. Many
pseudo-peaks (spurious peaks not corresponding to a real source) are produced by focused …

This paper considers the Cramér–Rao lower Bound (CRB) for the source localization
problem in the near field. More specifically, we use the exact expression of the delay …

Passive localization commonly consists of a two steps strategy. In the first step, intermediate
parameters, often called measurements (such as angles of arrival (AOA), times of arrival …

Localization of near-field sources requires sophisticated estimation algorithms. In this paper,
we propose an unconditional maximum likelihood method for estimating direction of arrival …

In fifth-generation (5G) wireless communications, large-scale arrays pose a challenge to the
accuracy of signal models based on the plane wavefront. In this paper, a novel method for …
