Comparison of conventional and subspace based algorithms to estimate Direction of Arrival (DOA)
2016 International Conference on Communication and Signal Processing (ICCSP), 2016The Direction of Arrival (DOA) technology and researches are evolving areas in array signal processing. Biomedicine, sonar, radar, seismology, astronomy communication and earthquake widely use this estimation. We receive an incoming wave by sensing an array or a set of arrays, this sensed wave can be processed to derive many related estimation ...

Performance enhancement of aperture antennas used for estimation of Direction of Arrival (DOA)
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014In this paper, we propose a method based on signal processing techniques to improve the performance of aperture antennas, such as a parabolic reflector, used to estimate the Direction of Arrival (DOA) of a signal. Three signal processing algorithms are investigated, including the correlation method, which is used to make an initial estimate of the ...

Virtural receiving array (VRA) method for direction of arrival (DOA) estimation
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012Using the data from a signal-element receiver on a moving Unmanned Arial Vehicle (UAV), this paper introduces a VRA method to obtain the data that can be used in the Direct Data Domain (D3) method for the signal DOA estimation.

IEEE Transactions on Vehicular Technology, 2002
An effective technique in estimating the directions of arrival (DOAs) of incoming signals using three orthogonal sensors is proposed. The channel model with multipath transmissions for code-division multiple access (CDMA) users whose signals are modulated with binary phase-shift keying (BPSK) is used.

Antennas and Propagation Society Symposium 1991 Digest, 2002
The authors present an analysis of the DOA estimation problem in a practical situation of multipath communication where a number of signal components are involved at each input cluster. Secondary, a novel technique is provided for an accurate estimation of the DOA of each cluster.

Spiral-shaped piezoelectric sensors for Lamb waves direction of arrival (DoA) estimation
Smart Materials and Structures, 2018Abstract A novel strategy to design piezoelectric sensors suited for direction of arrival (DoA) estimation of incoming Lamb waves is presented in this work. The designed sensor is composed by two piezoelectric patches (P1, P2) bonded on the structure to be inspected.

Comparative Study of Wideband Subspace Direction of Arrival (DOA) estimation methods
The Journal of the Acoustical Society of America, 2008Signal subspace Methods like ESPRIT, MUSIC and MATRIX PENCIL, provides high resolution Direction Of Arrival (DOA) estimation in comparison to traditional Delay and Sum and Capon methods, which are limited by sensor spacing. However underwater Acoustics signals are inherently wideband in nature and most of these Subspace methods works on narrowband ...
