Direction of arrival (DOA) estimation is an important problem in array signal processing. An
effective multiple signal classification (MUSIC) method based on the short-time Fourier …

Time-frequency analysis was combined with array processing to develop a direction of
arrival (DOA) estimation method. Spatial time-frequency distribution (STFD) was introduced …

Time–frequency (TF) approaches are frequently employed for source localization at low
signal to noise ratio. However, TF approaches fail to achieve the desired performance for …

In this paper, a new method for fast direction-of-arrival (DOA) estimation with no
dependance on array configurations is proposed, which is referred to as the symmetrical …

This paper proposes a method for efficient Direction-of-Arrival (DOA) estimation of coherent
and non-stationary sources under adverse noise conditions. The method consists of three …

Abstract Direction-of-arrival (DOA) estimation consists of locating closely spaced sources
impinging from different directions in the presence of considerable noise or interference …

In this paper, we present a tree-structured frequency-space-frequency (FSF) multiple signal
classification (MUSIC)-based algorithm for joint estimation of the directions of arrival (DOAs) …

In this paper, a novel method called fourth-order spatiotemporal algorithm (FOSA) is
presented for classification, 2D DOA estimation and 3D localization of mixed near-field and …

One of the main goals of time–frequency (TF) signal representations in non-stationary array
processing is to equip multi-antenna receivers with the ability to separate sources in the TF …
