Two Dimensional Angle of Arrival Estimation
CoRR, 2016 We present a new method for the estimation of two dimensional (2D) angles of arrival (AOAs), namely, azimuth and incidence angles of multiple narrowband signals of same frequency in the far field of antenna array.

Radio Interferometric Angle of Arrival Estimation [PDF]
, 2010 Several localization algorithms exist for wireless sensor networks that use angle of arrival measurements to estimate node position. However, there are limited options for actually obtaining the angle of arrival using resource-constrained devices. In this paper, we describe a radio interferometric technique for determining bearings from an anchor node ...

Polynomial subspace decomposition for broadband angle of arrival estimation [PDF]
, 2014 In this paper we study the impact of polynomial or broadband subspace decompositions on any subsequent processing, which here uses the example of a broadband angle of arrival estimation technique using a recently proposed polynomial MUSIC (P-MUSIC ...

Optimal Precoders for Tracking the AoD and AoA of a mm-Wave Path [PDF]
, 2018 In millimeter-wave channels, most of the received energy is carried by a few paths. Traditional precoders sweep the angle-of-departure (AoD) and angle-of-arrival (AoA) space with directional precoders to identify directions with largest power.

Robust spiked random matrices and a robust G-MUSIC estimator [PDF]
, 2014 A class of robust estimators of scatter applied to information-plus-impulsive noise samples is studied, where the sample information matrix is assumed of low rank; this generalizes the study of (Couillet et al., 2013b) to spiked random matrix models.

Robust Pilot Decontamination Based on Joint Angle and Power Domain Discrimination [PDF]
, 2016 We address the problem of noise and interference corrupted channel estimation in massive MIMO systems. Interference, which originates from pilot reuse (or contamination), can in principle be discriminated on the basis of the distributions of path angles ...

Sidelobe Suppression for Robust Beamformer via The Mixed Norm Constraint [PDF]
, 2011 Applying a sparse constraint on the beam pattern has been suggested to suppress the sidelobe of the minimum variance distortionless response (MVDR) beamformer recently.
