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 ...

Fundamental limits of single anchor-based cooperative localization in millimeter wave systems
EURASIP Journal on Advances in Signal Processing, 2020 Thanks to massive antenna arrays in millimeter wave communications, a much higher resolution can be achieved for the estimation of angle of arrival. By taking full advantage of beamforming capability and high angular resolution in millimeter wave systems,

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 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 ...

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.
