A DOA estimation algorithm based on equalization-cancellation theory [PDF]

, 2010
Direction of arrival (DOA) estimation plays an important role in multi-channel (binaural) speech enhancement systems and auditory humanoid robots. A number of localization methods have been presented, however, most of them require a large array of ...

DOA Estimation of Completely Polarized Signals by One-Bit Cross-Dipole Arrays

IEEE Access
The one-bit cross-dipole array employs one-bit quantization to reduce the sampling system overhead while extracting polarization information from electromagnetic signals, thereby lowering the system complexity of the polarization array.

Novel two-dimensional DOA estimation with L-shaped array

EURASIP Journal on Advances in Signal Processing, 2011
Two-dimensional (2D) direction-of-arrival (DOA) estimation has played an important role in array signal processing. In this article, we address a problem of bind 2D-DOA estimation with L-shaped array.

Direction-of-arrival estimation using a mixed ℓ₂,₀ norm approximation

A set of vectors is called jointly sparse when its elements share a common sparsity pattern. We demonstrate how the direction-of-arrival (DOA) estimation problem can be cast as the problem of recovering a joint-sparse representation.

Fast high-resolution techniques applied to the Direction of Arrival (DOA) of signals problem [PDF]

, 1992
Subspace decomposition methods are a very useful technique to extract the signal information via Eigen-based estimators. Although these techniques are very accurate, they are usually expensive to update, becoming difficult to implement for real-life ...
