A Simple Cross Correlation Switched Beam System (XSBS) for Angle of Arrival Estimation
IEEE Access, 2017 We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with a single radio frequency ...

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.

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,

Gaussian Channel Model for Mobile Multipath Environment
EURASIP Journal on Advances in Signal Processing, 2004 A model of an angle-spread source is described, termed the “Gaussian channel model” (GCM). This model is used to represent signals transmitted between a user equipment and a cellular base station.
