On single snapshot direction-of-arrival estimation
2017 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2017There are many algorithms for direction-of-arrival (DoA) estimation in array signal processing. Most of the work is carried out in scenarios with a large number of available snapshots. That is, received signals are sampled for a certain time duration. This paper focuses on worst case scenarios of having only one signal snapshot available, while trying ...

A novel direction of arrival estimator
Journal of Electronics (China), 2004A Direction Of Arrival(DOA) estimator based on the signal separation principle is introduced, and one of representative multidimensional estimators is established by introducing Matrix Operator projection signal steering Vector Excision(MOVE) operation.

Direction of arrival estimation by subspace methods
International Conference on Acoustics, Speech, and Signal Processing, 2002It is demonstrated that a Bayesian analysis can be simplified and can lead to a practical direction-of-arrival (DOA) estimator. This estimator is remarkably similar to the MUSIC algorithm, but has a threshold which is significantly lower than that for MUSIC. The reason for this improvement in performance is identified.

Compressive frequency-difference direction-of-arrival estimation
The Journal of the Acoustical Society of America, 2023Direction-of-arrival estimation is difficult for signals spatially undersampled by more than half the wavelength. Frequency-difference beamforming [Abadi, Song, and Dowling (2012). J. Acoust. Soc. Am. 132, 3018–3029] offers an alternative approach to avoid such spatial aliasing by using multifrequency signals and processing them at a lower frequency ...

Direction of Arrival Estimation with Uniform Planar Array
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017Analog/digital/hybrid beamformer/receiver designs for mmWave communication have attracted great research attentions including directional of arrival (DOA) estimation. Traditional investigation of smart antennas for wireless communications has primarily focused on uniform linear array (ULA) antennas and there are little attention and literature on other

Wavelet packets-based direction-of-arrival estimation
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004Wavelet packets-based MUSIC (WP-MUSIC) is proposed to improve the performance of classical MUSIC in scenarios of closely spaced DOA and low signal-to-noise ratio (SNR). With WP-MUSIC the fullband signal is decomposed into several subbands by wavelet packets, and then MUSIC is applied to each subband.

Direction-of-Arrival Estimation in the Presence of Phase Noise
IEEE Communications Letters, 2020This letter proposes a robust direction-of-arrival (DoA) estimator in the presence of phase noise (PN). For a multi-antenna system with independent oscillators, the received signals will be corrupted by multiple independent PN sources, resulting in severe performance degradation of the DoA estimator, especially for millimeter-wave systems. However, due

Subspace estimators of direction of arrival
Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005We consider in this paper a class of techniques for the estimation of the direction of arrival of a narrowband signal. Eigenvectors of a spectral covariance matrix corresponding to a number of the lowest eigenvalues are used to estimate the bearing. It is shown that the estimator has a non-standard asymptotic distribution.

Direction-of-arrival estimation of an amplitude-distorted wavefront
IEEE Transactions on Signal Processing, 2001In a number of array signal processing applications, such as underwater source localization, the propagation medium is not homogeneous, which causes a distortion of the wavefront received by the array. There has been some interest in the direction-of-arrival (DOA) estimation of such distorted wavefronts.
